Mazda RX8 Engine/Trans Question?

I am considering getting a 2004 mazda rx8 automatic. I am familiar with the cars engine as a four port engine mated to a 4 speed auto (and the host of issues they tend to suffer from). Since the only car in my budget/preference range is a 2004 with 78K miles, I was wondering if I should just swap in a newer engine from a donor RX8. I am considering putting in a 2006 engine and transmission as the engine is a 6 port engine mated to a 6 Speed auto. I am wondering if this is possible. I believe I should also just need the ECM from a 2006, but since I am not 100% car savvy, I am trying to figure out three things.

1. Can this be done?
2. What parts would I need besides the engine, trans and ECM?
3. Is this Worth considering, or just check and see if the car is still under mazdas 100K mile engine warranty and just leave the engine alone for the time being till I dies?

Thanks!!
 
First, check out the warranty issue.
Then read up on issues that go with this swap, Mazda seems to change the way the engine is mounted every time it brings out a major engine redesign.
More then likely the best help will come from the RX8 Club, or a site like it.
