Suggestions?

If you have a standalone that allows separate injector characteristics for different injector banks, then yes, that would solve the issue. Actually in that case, the ECU probably supports low impedance on one bank and high on another, so you wouldn't have any issue at all. Problem is, I'm unaware off the top of my head of any standalone ECU that does support that setup, save perhaps a Megasquirt, which has two totally separate injector driver circuits, and the software to tell it to use pulsewidth modulation and load clamping on the low impedance injectors, and full 12v on the high impedance side.
As for putting in low impedance injectors for primaries and using resistors all around, if you go standalone, just let them all be low impedance; just so long as you're not mixing, you'll be fine on almost any standalone. The only time you'd need to do that is if you're staying with the stock ECU.
