I could see that being a problem myself. I'm pretty sure that the 4ag engine could use the distributors from the 4af engines so it was a easy swap, on an sr you would have to custom make something to work or do something like a mega squirt to control just the ignition.
It sounds like a fun project but I doubt that you would be able to match the power of a stock DET and you would probably be spending a lot more money and frustration on it.
I guess I'm just saying think of the functionality and investment (time, money and downtime) aside from the fact that it will be unique.
