Electronic OMP

Possible, yes; don't know of any that exist, though. You'd be into a research project to find a reliable 12VDC pump that could deliver the right amount of oil & reach to RPM.
There is a mechanical adapter out there that will replace your metering pump and meter oil from a separate tank. There are threads on it in here somewhere.
In the meantime, you could just wire the control arm of your OMP in the open position... you'd use more oil than necessary, but you'd at least be operational.

You would have to somehow control the pump based on RPM. I think the 3rd gen did this with the ECU. You would also want some sort of fault detection. If the pump lost it's control signal, the pump would be placed in wide open mode. I would also want to know if the pump stopped working.

Heres a site with some pics of the electric OMP and a gsl front cover.

I wonder if you put smaller lines on the mechanical omp and left it in the open position could you make it deliver a steady flow of oil at a smaller rate putting enough oil to the rotors?

sell it and buy a stock one?
the electric pump requires a stepper motor driver and then it has a position sensor the tells the ecu it did what it was told. its like a drive by wire throttle body.
kind of a lot of work to hook it up, needs rpm, coolant temp, and load to work like stock.
the mechanical one can be cable driven

Just read your sig. I take it your running the S5 intake which was the first model with electronic MOP. I'm guessing you aren't running the stock ecu. Steve84gs had his front cover modded to accept the S5 mop on an SE front cover. He kept the stock ecu though though for emissions.
To adapt the E-MOP you'll need to gather all the oem parts needed for it's operation, mod the front cover and perhaps find someone to write code for your standalone. I'd just pre-mix.

from that link,, i cant see an operational EOMP on that GSL-SE timing cover
instead,, he refits the 4 way GSL-SE oiler
-- trust me,, i would be very interested in seeing a solution,,that allows the 3 bolt EOMP onto a 12a timing cover but i have hit all these snags before
also to boot,, 12a and s4 water pump outlets will interfere with any s5 EOMP
-- indeed in the linked pics , he shows you the clash of the water pump housings when trying to fit the s5 waterpump to a 12a/s4/GSL-SE timing cover
( necessary if you have EOMP )
now ,, as for control,, i have helped develop a stand alone EOMP stepper controller
( that will use a 1- 5 V load signal from the wide range TPS or from a map sensor ,, with a user adjustable offset bias )
so you can PM me if thats your ticket

( put in a longer thread and it will stay fixed at whatever you leave it at )
as is,, i think the old 12a unit is 1.8 CC per minute at 2000 rpm ,, and the GSL-SE 4 way is 2.2 CC
at full rate with those,, i would check levels once a month
PS
its not hard,, and doesnt take much imagination ,, to drill a hole in part of the s5 throttle lever mech
and hook up a bicycle cable and sheath to control the mech OMP
