Kurt,
at the ranges you attend, the course of fire is three strings of 20 rounds for record + sighter at 100 yards, correct?
If this works for an NRA approved match and the participants can earn classification then this is perfect!!!
I volunteered to look into this and set up some matches at out local range. We have a sizable group of older shooters who want to keep shooting but no longer want to deal with recoil. Several of the folks have grand kids that they want to get involved. Not lugging gear from one yardage to another would help them a bunch. In the summer heat here in western Colorado a 160 round match might run off some of the older fellas.
I've got a lot to learn.

There is a tradeoff there.
Smallbore requires 200 shots for classification.
If you have a shorter cof then it will require more days to get there.
Also, even if you craft your cof for f-class in particular it will still be a legal cof for metric prone.
Might as well leave it open for sling shooters too.
