I think it's great story idea and I think perhaps it could be used to great effect between the two. Lex pushing for morally dubious means of making sure the government has a counter to superheroes if they ever go rogue while Clark and Lois try to expose him. Lex putting Waller in charge of the DEO and putting ARGUS and SHADE, as well as Checkmate, under her control could be very interesting. I think honestly it would've been great to have it run for a couple of years also as a means of letting other supervillains take the status of top dog in Metropolis while Lex is in the White House. I thought the fall of Lex was great, his own pride and arrogance plus his need to upstage Superman does him in.
