Although I agree an appearance change for SMN would be awesome when they go into DT. However there is one key difference between us and Iceheart, which is that she is using her body as a vessel for ALL of the Aether, allowing the Primal Shiva to be born. Shiva was not a Primal before this point.

With DT we are only summoning/absorbing a small portion of Bahamut's Aether, so any physical change in the SMN would probably be small. If there was to be a transformation introduced, personally I would like to see something similar to FFIX's Trance mode.
