You've got two choices, either...........1)calculate the "RL" equivalent of
your new circuit, and deduce whether or not things will work with the
current driver that you have, or..........2)run your setup on a test bench.
Test bench time should be proportional to real world operating time.

Personally, I'd use an external injector driver, either purchased
"off-the-shelf" or homemade.
