According to the Wookieepedia page for List of Legends elements in the films:
“…we’re inspired by the comics and the books…” ― George Lucas
so it sure is a possibility.
Is the old Marvel comic you refer to the Star Wars 68: The Search Begins?
I’ll have to try and get my hands on some of those old comics again, and give them another read. If that is the comic, then I remember it being pretty cool. So it would be a shame if that was the inspiration for what would become some of the lame execution for the Clones and whole Clone Wars backstory in the Prequels.
i also think he was inspired by Tales of the Jedi and Dark Empire Comics for the Prequels supposedly George helped in the creation of Tales of the Jedi
There is a really good article somewhere listing many of Tom Veitch’s contributions and ideas from his EU work that later made their way into the films and series. I’ll see if I can find it, maybe at CBR or comicbook, at some place like that.
I think the New Jedi Order also has some stuff in that Lucas was going to use, or was inspired by, for his unused Sequel Trilogy ideas too. I know next to jack about the EU compared to others, but these folks seems to believe so on the NJO stuff:

Though more knowledgeable heads on here will know far more than me.
Yes it was that Comic the Clones are practically Clones of Boba Fett in Lucas Prequels there is also an image of Young Obi Wan during the Clone Wars with a Black Suit similar to Luke the Threads you left are interesting
