how about 2 sets of injectors
use both with the alcohol fuel and only the main set with gas
then you can run only one fuel map and adjust the 2nd injector size/pressure to
maintian fuel curve values
alcohol does not have to run rich, it can be made to run clean with a little
tweaking

nitrometh needs a lot of timing advance, it is hard to light
but you should be able to do this

in solution it should be fine, pure water may not be too great for injectors
but you have the fuel as a lubricant anyways

indivudual injectors are better across the entire range, and give better
fuel control, distribution and tunability

Turbo and High Tech performance magazine lists a number of these
