You cant really find e85 commonly in Vancouver since our fuel stock come from Calgary not from Mid West. Any ethanol we have is limited to the additive fuel pack that is added (which is minuscule). If cooling is your concern, Lexus engines uses both port side injection and DI to cool down the fuel, that is not limited to e85 fuel.
For DI you can't really make a business to make aftermarket injectors since the injectors spray patterns are often designed for a particular head design. I don't think any indy firm can best the CFD resources the OE manufacturers had spent on the combustion chamber design. Besides you don't really need to, if you really want to increase the amount fo fuel that the injectors squirt out, just modify the PWM interval.

The Cobb AP allows for increase fueling to deal with the lower energy content, however, the platform is still fuel limited when running E85 mixes as no one makes aftermarket injectors.
