I’m trying to figure out a solution to this same problem as the OP. I’m currently using a DBW TB, but I can make the switch to cable, if it’s the only way to make it work.
Thanks for any guidance.

Cable operated TB. FAST/Accufab 4150 (4x44mm) comes with morse ball and F&B 2x58mm can be optioned for a morse ball. Single blade I am still working on, but i'm told that if you can get through to Accufab or Holley tech support, that it's possible to have a morse ball linkage made for their 90-105mm TB's. Worse case, there are 10" cable-wrap to 10-24 morse stud adapters made. But I hate cable-wrap TB's because you can't use a toe hook if it hangs open- it will just push the cable off the guide rather than push the blade closed.
A blade stop will not work with EFI for same reason it won't work with Enderle/Rons injection. You can restrict the airflow all you want, but the barrel valve or ECU TPS will still see WOT and be dumping fuel in.
Just for my 2¢ , I agree (especially in my case of being on the heavy side for factory interior; essentially super stock trim) that coming on the stop in high gear will control wheel speed but lose MPH and possible consistency from the motor lugging from basically a 20-30 MPH roll in high gear. On the other hand, coming off the stop in low gear may yield a traction limited situation depending on how the boost curve comes in.
I'd like to think that even at 9" wide, a 30" tire with a powerglide and 3.89 gear would be pretty damn hard to spin coming off the stop in low gear. But again, depends on the boost curve.
