Well, anything is possible with enough fabrication.

The pushrod may be designed to have that extra 2 or 3 inches of booster there, so it may need to be cut down. Other than that I would really worry about your brakes working well. Try disconnecting the booster or just rolling and trying to stop with the engine off after the vacuum has bled off... unless you're the iron man, I wouldn't want to try to stop it with unassisted brakes.
