Yes, Jake, you will be all right at that. I fitted new pistons and rings to my RP a few weeks ago and the ring gaps were of the order that yours are. just make sure that, when you fit the pistons, don't align the gaps. I set mine at 120 degrees from each other for 3 ring pistons and 90 degrees for 4 ring ones.
I used a honing tool to deglaze the bores and to take off the (slight) ridge at the top of the bores. Alternatively, if your top ring is stepped make sure the step is to the top and don't worry about the ridge. Big Sevens don't suffer from crank whip like ordinary Sevens.
