You could just have the second gear synchro replaced. I can't imagine it being all that expensive compared the a 6speed tranny swap which would probably be a custom job.

5-speed trannies are much easier to rebuild than the 6-speed. 5-speed tranny can also hold plenty of power. On the other hand, finding a clutch for the 5-speed that can support high HP output may be more diffucult than swapping in a 6-speed 
Swapping a 6-speed isn't difficult. I have done that with my NA auto. The 6-speed gearing does not match well with the differential ratio and the HP output of the car. Let's just say that you can start your car from a complete stop in 3rd, maybe 4th.
5-speed gear ratio:
3.285
1.894
1.275
1.000
0.783
3.768 (reverse)
4.083 (differential)
Japanese NA Supra come with 6-speed as an option since 1995 (or 1996). It uses 3.769 differential ratio, which is the same as the TT auto.
