Replace a Briggs 15hp 1-cylinder with a Briggs twin?

Has anyone ever replaced a single-cylinder briggs with a twin-cylinder briggs? Are the bolt patterns and shafts generally similar selections?

I have a rider that I'm working on for a friend, has a cracked block, but having trouble finding a replacement engine, but have found numerous twin engines in my area... Might just have to go look at one and measure everything out. Just wanted to see if anyone has seen it done.

It can be done. The bolt holes are usually there, the shafts can be different but are usually the same. The wiring may be different and the throttles will almost certainly not interchange. The exhaust may require some modification.
