yes thats what most people do, even tho with RNG abuse they are is no much point of it since the same pokes with different OT's are everywhere.
Although, now with B/W out and until the RNG gets cracked there, the rights thing is going to be used A LOT(Since it wont be so easy to get a pokemon and dont forget there are like 400 pokemon which can be used competitively and had to be bred in B/W)
