I don't think so. Marvel 2 pretty much improved on the earlier games all-around, so picking that up for online play would probably be the better option. I don't know how active Marvel Origins is online either.
I think Marvel 2 is a downgrade in every way from just about every previous capcom vs or marvel title.
But I can't find anybody online in Marvel Origins, so I couldn't recommend it if you plan on playing online for competition.
