Ya, I guess you're correct. I didn't figure in the fittings, filter and stuff.
This is what I made to fit my Aqualine tanks after finding the the peice of inner tube rubber they give you as a seal failed, only to find about 5 gallons of fuel on the garage floor in morning. Good thing I don't smoke.
I'm not 100% sure this would fit on a 990, but it work on these tanks meant to fit the stock pump.
After looking into the cost of materials and time, about $50 sounds real close for the plate and viton O-ring.
An older model pump from a FI sport bike like you said might work.
If someone needs a plate and wants to run w/ this idea testing pumps and whatnot let me know. I could make another up for test purposes, before I make a larger batch.
I would think that this "kit" would be put on "Before" the stock dies if heading out on a long trip. If anything just carry another pump, easier to install like the 950 version.

total system components:
fuel pump: ~$100
990 tank plate: ~$50 (total guess)
fuel filter: ~$20
various fittings and hoses: ~$30
thoughts CJ? am I way off costs? is there another way?
I know that the FI in my old CBR600 FI tank mounted pump (and many other M/C systems) just dead headed to the fuel rail without return fuel to the tank like in a car, so maybe return fuel and adjustable FPR is not necessary.
Would something like this bolt on to the stock tanks?
