Thanks!
Unfortunately full-RBF is probably not going to help you with those closes, as it's more likely that they don't meet the minimum relay fee (I assume they're force closes).
The ViaBTC and Binance transaction accelerators could help out. As will the mempool.space one, which is a lot cheaper. But not publicly available yet.
It's one of those things I believe I will eventually figure out but I wont hold my breath. I signed up for the mempool thing and "we'll see."
