Paul,
Are we thinking along the same lines i.e. using your suggested bolts

like

the 2.17 toothed flange is used to hold the 2.17 planetary.
If so that a good idea, my only concern is drilling into the ring gear

and

going right through the teeth.

Don't drill into it. Just grind a few small shallow depressions where
the set screws go.

Paul,
My old mate suggested another way of doing it and that was through the
housing with a bolt (as you suggested) but in this case, bevel the bolt end
to slot into the outer splined section.

Do you think that would be good enough?

I noticed with the 2.85 Ross there were two spring rolled pins (only)
holding the Ring gear in those same splined slots. This was visible as the
ring gear was turned around to accommodate the pins from the open end.

Sure if you use about six of them. Tracy is considering doing it the expensive
way with a bulkhead screwed to the housing.
