I see what you are getting at and there are people that level at different speeds. I personally would rather just create a new character than have everything wiped though.
I do like the idea that SOE was trying things out with separate servers for these choices though.
How often would they wipe the test servers? I never tried those and heard they did wipes from time to time.

another suggestion:
Perma-death means perma-death. when you die, your character gets deleted and you're kicked back to character selection (with a newly-opened slot)
