Does anyone make a fuel pressure regulator controlled by a fuel composition sensor? In terms of E85 and varying blends.
Does anyone make a boost referenced fuel pressure regulator that would vary base pressure based on alcohol content?
I did some searching but haven't come up with anything yet.

Unfortunately the regulator would have to be capable of very high pressures.
Remember to get a 25% increase in fuel flow, the fuel pressure has to double. This would render most pumps useless except for all but very low pressure/low flow systems.

Not for the purpose of being able to run gasoline and E85, just so if you always ran E85 it could self compensate for variances in alcohol content you could see at the pump.

Misunderstood your question... based on the small % variance of E85 only blends, yes it could work as long as you never intended to add plain gasoline as the pressure difference would be huge.
Unfortunately that device could not be fully mechanical so the sensor is still electronic... meaning with the cost of the sensor will not be cheap.
Adding a pulse width modulated, or electronic pressure regulator with a single loop electronic controller is possible, but not cheap. I'm an engineer involved with digital controls, valves & regulators used in the gas & petroleum industry. It is not that hard to do, but definitely not cheap. Typically it would be easier & cheaper to go with the E85 firmware which is available from many OEM's, especially if using an LS based GM computer.
Wish I had a good answer for you.

There is a module sold at change2e85.com it is simply a plugs in between each fuel injector and harness, and has a controller. Its to turn your car into a flex fuel car. They say it changes the algorithm to the injector to make your car run properly. I would guess it would need to be able to compensate for variation of e85 at the pump. Im not sure if it does it at the resolution you are looking for, but its worth a shot. A couple of phone calls may give you the answer your looking for. good luck
