Quite a few options.
Another Taylor T5z suggestion, it would cover everything you need. Godin has a few models that will do this as well, and give you Synth access:

Steve Benford, Benford Guitars, will build you a custom Tele with a Piezo system, his guitars are terrific, and his pricing is incredibly reasonable.
If you can find a used model, Fender had a Nashville Deluxe Power Telecaster that had a Fishman Piezo.
My experience with the Epi Ultra III wasn't great, strictly from a QC standpoint. If you go that route, check it over pretty well. The fit an finish on what was sent me, both the original and the replacement, both went back.
Finally, Kiesel offers acoustic saddles on some of their models. I have a Carvin (pre-Kiesel name change) CS624 with the acoustic saddle, beautiful guitar.
