Android :: Way To Trade Evo For Epic?

I know this is an evo thread but i figured i would just put it here because i still have the evo lol. so basically i got this evo about 2.5 months ago from BB, and had BB's insurance from day 1. My question is, i thought i would get better with typing on the on screen keyboard but i haven't and im just ready for a full qwerty again ( i had the g1 before). so im thinking is there ANY WAY at all i can try to go to BB and explain to them or even make up a reason where my phone isn't working properly or whatever and tell them that i have their insurance, and then maybe ask them if i can trade it in for an epic (obviously im willing to pay the difference)? And just another question, if this is possible can i just tell them to keep my insurance plan the same or would i have to reopen a new insurance policy for the phone? I'm sorry again if this is in the wrong place, but I wasn't sure where to put it plus this forum is very helpful.
