If the car is only ever cruised around, doesn't see hard launches or anything like that, you can probably get away with it. If you drive the car spiritedly you'll likely need to keep the tank at least about half full at all times.

I run a Tanks Inc setup in my bird and it's absolutely as good as it sounds. Hard acceleration, braking, hard cornering, even below 1/4 tank I've never had fuel starvation with my setup. Like you I tried saving a couple hundred at first on the fuel system, only to fight the car, end up tearing it out and doing what I should have done in the first place, which is the EFI ready tank and fuel pump.

I run a Walbro 255 and a Vette regulator on the frame of my T/A, and use the stock sending unit as my fuel pickup.

I wheel the hell out of it, and haven't experienced any fuel starvation, but I also dont run it down to E. I have had it down close to an 1/8th before, and it's been fine. That said, there are some cars where the tanks just can't help sucking up air if they have less than a 1/2 tank.
