I think its plausible.... xr6T does 5.1, NOT RUN IN then I believe a typhoon will easy do 4.8 or 4.9, and 4.7 definately is in the realm of possibilities. The difference between ba/bf T and the F6 were worlds apart in driving feel, and im sure this will be the case again. With 30% less lag, quicker shifts then I say its possible(or not far off it) !
