Greg:
As long as you use a skivved mouth hull (like AA or STS), 2 3/4" hulls in a 2 1/2" gun are fine. The low pressure limit you mention is also fine. But... why use more than 7/8 oz. for any clay shoot? I use 3/4 oz. at under 1100 with perfect satisfaction in sporting clays. It's much better for older Brit guns as well.
Again, there is NO practical reason to use 1 1/8 oz. shot charges in these guns.
Best, Kensal
