I'd get the bowler up and running before you do anything crazy. It's not like you can just plug a head from another game in and expect it to work.

Bowling Alley is a coffin style game where a lot of the mechanicals are under the lane. 3-Way is a shuffle alley with all the game logic in the head. Not to mention I think your reasoning is to add two game options to your bowler but one of those on 3-Way is flash. Flash utilizes lit inserts on the lane that are not on the alley in your ball bowler.

There are guys that can do this sort of thing but it would require some serious re-engineering to make it all work. You'd be better to sell your Bowling Alley and put the money toward a later game if multiple games is super important.

Sure and I understand what your thinking. The Bowling Alley is neat game and I like '59 3-Way too. I really like this era of shuffle alley. It retains the charming woodrail style of an earlier machine but offers a few game options. I'd consider adding it if you have the room. Having two of them running would be much better than eliminating both to have one mixed up Frankenstein version in my opinion. And as mentioned if you wanted a multi-game ball bowler you'd have more to put toward it. That mash-up machine would be a tough sell later on.
