I’ll start off by saying, its obvious Tom Welling has no interest in playing the traditional Superman in tights, so that’s where this take he may would possibly consider.
Give this an “Elseworlds” label on in vein of the Joker film. Smallville already kind of is anyways.
Continuing where his Crisis cameo stopped, Clark Kent is powerless, but raising kids with Lois… but his kids have super powers. That would be an interesting dynamic in itself. Especially how would this Clark raise them. Would they want to be normal too or keep their powers? Also exploring Clark Kent without super powers. Him wanting to save people from certain death but realizing he can’t do that anymore and how does he cope with it. Maybe eventually in the show, he could get his powers back. Since were not even sure how he lost them. Just leave the suit in the barn, maybe Welling would be down? He never needed the suit to be Superman anyways!
Could him and Lex be friends again?
Yeah, mostly will never happen. But Smallville has always been one of my favorite series. I think it still has a pretty decent following. Tom Welling’s Crisis scene is over 5 million views from just one video uploaded. So I think it would still do pretty well.
