Why dont you try it.

I really don't think that Premiere is going to do anything bad to your footage just because it's AVCHD. Premiere doesn't care what the format is, it just uncompresses it and works with the resulting frames. The format they started as shouldn't matter at all when compositing titles etc.
One thing that comes to mind is that if you import 8-bit footage, a bad NLE might work in 8 bits throughout; whereas if you transcode to 10 bit, the NLE might then do all the compositing in 10 bits, which would produce better results. However, I'm pretty sure that Premiere is smarter than that and always uses more resolution.
