Ive been doing some thinking on this one

What you need is a fuel only computer. Crank angle sensor and a TPS.
Keep the std reed block, in the same location. Use a machined alloy throttle body blank (i think a webber side draft would do) with 4 tiny injectors.
You would tune it off the tps and rpm inputs. Thats all you need really. You could incorperate a MAP sensor as well (NOT a AFM), but this makes tuning more diffcult, as you get a 3d map, not a 2d map
Basically, you'll have something like 10 mapping points at 250rpm intervals up to 15000 rpm. So 10 different throtle positions, that can be altered every 250 rpm.
You would just have to play with injector pulse timing and duration.

I would keep the std NSR spark control.
