I think the best of both worlds would be if I could make an account on both and have one account essentially repost anything from the main account, unless I’m replying to someone specifically where it wouldn’t make sense to reply on both accounts.

That’s what I’d want from a bridge - something to connect an account at each end. If/when Bluesky suffers enshittification, it would mean that folks on Bluesky could just switch the direction of the bridge and start posting in the Fediverse. No sunk cost leaving you hanging on, no high barrier to moving.
