Certainly a later tranny would be the simplest approach, and could take care of another issue - that of mis-matched gears since the pilot shaft drives the countershaft, the result of a new single-plate pilot shaft might be noisey first and second gear operation.
With my '28, I swapped the whole engine and transmission with a unit from a '30 depression tractor (that I bought for $30 - ah - the good old days).
The location of the crack is the key to success. Properly handling the ends of the crack is paramount. Normally a hole is drilled at the ends of a crack to provide stress relief and to prevent the crack from spreading.If the crack is in an area that is subject to mechanical stress, or heavy thermal variation the likelyhood of success is somewhat more questionable.The whole question may be moot, though if you haven't inspected the top of the block for cracks between cylinders and radiating around the valve seats.Clean it down well and see if there's signs of cracking particularly at the front and rear of the block and in the distributer area.Water jackets are one thing, but deck repairs are quite another.Most automotive machine shops can check this for you if you're not sure.
I'm sorry, but I don't know about Mac's track record on rebuilds so I can't comment there
