but I think I'd like to see Deathstroke and Dr. Doom switch places....I think Doom in DC would be very interesting...he'd be starting without all of his resources, but I'm sure he'd build an impressive power base quickly.

Likewise, I think Deathstroke would be interesting in the MU.

Taskmaster through the late 90's had a very strong track record, and back then, he may well have been REALLY interesting in the DCU as well...training villains etc....if I switched him out, I think I'd swap him with classic Blue Devil as he was during the end of his solo series, because I'd like to see him interact with some classic Spidey villains.
