I cannot see a reall problem.   Electrically the higher resistant
would require less current which would be less likely to burn out
something.  Now things would not be a problem so long as the higher
ohm injector needed to be driven by a different (not 12v) voltage.

I believe I actually went from a GM injector (that was about 12-13) to
a Ford SVO injector (about 15) and have been running that for over a
year with no issues.
