So use individual MAP sensors, but have a 2nd port in each runner for
the fuel pressure. Or just hook the FPR to a single runner since it's
likely to be close enough to the rest of them for a "low-tech" FPR
anyway.

The system I'm working on treats each cylinder as it's own engine, but I
only have 2 cylinders to deal with and no need for any vacuum/MAP
reference of any kind. Not the most precise way of controlling fuel, but
it's close enough. With an engine that can see 5000 rpm and 11000 rpm in
under a second there's more important things to worry about ;) MAP and
MAF just aren't fast enough. Closed loop and loopup tables based on RPM
and TPS will handle it if the processor is fast enough. Now to worry
about that fuel atomization issue...
