I mostly missed MARVEL COMICS PRESENTS' entire run, but I know there was quality stuff in there like Barry Windsor-Smith's WEAPON X, and I was happy to get the collected "Panther's Quest" by Don McGregor and Gene Colan.

++++++++++++++++++++++

The problem with SUPER TEAM FAMILY is that some stories were reprints. I had issue #8 (the Challengers of the Unknown fighting a  T-Rex on the cover), and it and issues 9 and 10 included reprints of DOOM PATROL, for example.

So a SUPER TEAM FAMILY collection would include reprints of reprints.

As for TPBs, I'd like to see ALL-STAR SQUADRON collected. Couldn't care less about YOUNG ALL-STARS, however. Or the Golden Age JSA issues of ALL-STAR COMICS in TPB rather than hardback ("Archives") form.

I'd like to see a Marvel Premiere TPB. There was a variety of characters after the Iron Fist run that I don't think have been collected.

For DC, other than some of the ones already mentioned, the original Black Orchid run. Fun stories, great art.

ROM

I had long despaired of any collection of MASTER OF KUNG FU (for those legal entanglements), so I dutifully collected most of the single issues--and THEN they collected it!  Same thing with HOWARD THE DUCK!  So, don't give up on ROM just yet.

And I normally don't care for hardcovers, but I recall the Michael Golden issues of MICRONAUTS were just amazing-looking and could really shine in an oversized edition.

Wallace Sellars, I am right there with you on the Ramona Fradon Plastic Man idea, and Eric, a collection of those Bridwell/Newton Captain Marvel stories would be like a bolt straight from heaven. 

I'm also down with everyone suggesting the Rom, Micronauts, and Creeper collections. 

Marc Baptiste, back in 2001 and 2003, DC came out with two trades reprinting various issues of the Super Friends. I've long held these as examples of extremely poor editing as the first volume prints the first part of a two-parter and then goes out of it's way to avoid printing the second part (an art switch is done on Wonder Dog's reaction to the non-ending to make him perfectly okay with things ending on this note) while not reprinting the more logical starting point, Ramona Fradon's done-in-one first issue #3, which the characters in later issues refer to, but isn't included, in either volume one or two. Very irritating. 

There is also a Showcase Presents collection of the Super Friends.

One collection I was reminded by someone's mention of the Superman Family that still doesn't exist is the completely charming Mr. & Mrs. Superman feature from that series. Stories by Bridwell (mainly) and art by Schaffenberger (again, mainly) that were fun and very much in the spirit of the Fifties and Sixties. Schaffenberger's art would shine in a trade paperback and there is more than enough material to flesh out the page count if we include Action #484 and the back-up features from that era as well as the Superman Family issues where the Earth-2 Superman took center stage. 

Failing that, I have an even more extreme deep dive pick I'd like to see; a collection of Golden Age stories featuring Lois Lane's mendacious, overly-imaginative little niece, Susie Tompkins. She shows up in five or six stories from that era and returns for one appearance in the Mr. & Mrs. Superman feature. If you absolutely must, you can include the absolutely asinine Grant Morrison revisiting of the character wherein she's some sort of alien repository of meta-occurrences and extra-dimensional gobbledygook because, well, Morrison... Hey, it made perfect sense to him when he came up with it. The fact that he couldn't communicate it on the page is your fault. You're stupid. He'll take that next award now, thank you...

I'll put up with it to get the other stuff. C'mon, Susie Tompkins fans! It's 2020! Lying has never been popular or effective! 

One thing leads to another!  Talk of MICRONAUTS makes me wish for a Michael Golden collection of his DC work, half of which is Batman-related.

And that leads me to wanting some nice collections of Neal Adams' Continuity Comics!  But I don't know where you'd draw the line there though.  Most of them started off better than they ended.  (I really liked the first three appearances of MS. MYSTIC and MEGALITH/REVENGERS!)  But then, none of them really ended, right?  CYBER-RAD was the most consistent, but that trailed off too, didn't it?

And getting back to our host--was DOOMSDAY +1 ever collected in any way?  And I don't suppose there's any way for me to ever see his SPACE 1999 or other Charlton moments all together?
