aside from the DE having 4 extra valves, another cam, oil quirters, different tach and speedo outputs, and im sure 20 other things different, YEAH SURE IT WOULD WORK. idiot.
You might want to know a thing or two before you go calling other people idiots, because it makes you look pretty stupid. It is a very good question. Anyways out of the above things you mentioned, the tach is the only relevant part as it requires a signal from the dist. which is different on the dohc ka. Driving the injectors would not be much of a problem as both are high impedence and similar flow rate (260cc).
There are two problems that i can see with doing something like this. 1. distributor, i do not know the exact differences in dohc/sohc dist (electronic advance, input signal to coil, tach output, etc...) Im sure there are some definate differences. 2. All of the senders (temp, iiav, cold start, etc.. etc...) would have to be transfered from the sohc to the dohc and work correctly for the sohc ecu to operate (because you would be using the sohc harness).
I have thought through this a few times in the past, really not to difficult to do. That is if your going to be using a sohc type dist.
