You are exactly right, all you need is a little stub distributor. In a pinch, you could use the whole distributor and just not connect anything to it. In fact, that has one advantage, and that is that you can install a cam sensor in the distributor for full sequential efi. Of course, you can install a cam sensor somewhere else, too.
What I did when I ran the stock oil pump on my SOHC with the individual coils was to cut an MSD distributor up and use that. I cut the body off in my lathe just above the groove for the seal, and then cut the shaft off about 3/8" higher than that. Then I machined a little disc that would bolt to the top of the distributor stub, that was about 3/4" thick. I counterbored it for a bearing that was 1" OD and 1/2" ID if I recall correctly, and then bolted it onto the top of the distributor hub so that the shaft inserted into the bearing. That way the shaft is supported by the bushing at the bottom of the distributor housing, and the bearing at the top. Then the whole thing just drops in place into the engine and clamps in place with the stock distributor clamp. It was really pretty easy, but of course I have a lathe here.
I'd post some pictures of this thing but currently it is in my big SOHC engine, so I can't. But don't let that problem stop you from running the individual coil efi system; that little stub distributor just isn't that difficult to make.
