I don't know if there is an order the nominations must follow to be approved, but if there is, Trump should place this as the last one to be voted on.
Based on what I have heard, from Jim Jordan and others, this nomination would definitely confirm that Trumps MAGA is pushing the old, entrenched Establishment out and replacing them with nominations of people who will protect the U.S Constitution and the U.S voters who demanded this change. If not, it may put into question his ability to control it all.
As one person said "the voters are watching. Will they get what they demanded?"
