Not a bad idea, but would it affect air flow? (I'm not at all familiar with
this engine, let alone the details of the engine and it's head/manifold.)

How about putting all four CIS injectors in a plenum under the throttle
body (a plenum is required for K-jetronic anyway). You might not get ideal
mixture distribution, but it would still be better than a carb (finer
atomization). Lots of Detroit products do fine with single-point injection
and still manage to run better than their ancestors with carburetors.

Not ideal, but probably less work than the alternative.
