I'd be more worried about spray patterns, atomization,
and flow rate with the much more viscous pre-mix
coming out of the injector nozzles.  If I wanted to
run pre-mix through an injector, I'd be prone to
redesign the injector to optimize for the viscosity
you'd be using.

You'd also need to, just like with carbs, change your
mapping (jetting) when you change brands of oil, as
they are different viscosities.

I'll be very interested to see how you do with it, and
especially what sort of comparative power and mileage
you get.
