You are only going to have one vestige per day (unless your group makes a Binder capstone feat for a second one, but those are usually limited to those who take a single class for 6 levels). You'll need to Bind Naberius to buff, so might want to consider buffing every other day (using Extend + Persist), and bind a different vestige on off days. If you do access to a second at the same time, Paimon offers a bonus to Perform (Dance).
