Yeah a Holley with Air Valve Secondary control,like the Carter AVS.
I did it,and it worked fairly well!
Made a seperate removable housing,with spring loaded air door,which is adjustible.
Took some High Speed Air Bleed tuning to get the fuel curve correct.
But it was awsome when the door kicked open in 2nd gear. Would blow the tires off!
