Q1 - Is a three speed box in a smaller case than a four speed? - YES
Q2 - Is a 1932 cross member taller than 1935? - YES, BUT with a high chassis crankcase there is clearance for a four speed box, unfortunately it sounds like you have a Low chassis Crankcase which has relocated mounting feet to suit the lowered drive line of the later cars, hence your clearance issues. Low frame front cross members have a dip in the centre to allow gearbox clearance.
Q3 - Is there a "well known fix" such as mounting the engine half an inch higher or something? - Its a special so you could raise the crankcase to gain some clearance but you need to be careful otherwise the drive line could end up with some funny angles and the nose piece won't fit through the radiator cowl. Probably a better plan long term to swap or alter the top of the front crossmember to a low chassis shape.
Q4 - Other than sourcing a prop and/or a converter to connect my box to his axle (he's on that) are there any other obvious "gotchas"? - As its a special this question is hard to answer but if you move things it could cause alignment issues with various other components such as pedals etc.
