Well... if you like challenges this is the right one to take.
In my opinion there are too many keyboard generations in-between to recover.
Hugest T2 gaps are:
SFF1 style format
Significant amount of missing voices (Mega, S.Art,Drum kits etc.)
Limited DSP capability
At the end of the story it would be difficult to maintain the "edge" or those styles,
so they would sound closely to the T2 ones...
But the very last word is on your side, it depends what your scope is.
