I don't think it's worth it. Frankly, if they're going to sign with another label, it should be with Rise. They're Rise's number one priority (I would imagine) because of their size and financial earnings (I would also imagine). There's no way they'd make more money with a major or get more promotion with a major.
It also went pretty poorly for Escape The Fate from Epitaph. I'd look at that as an example towards why I wouldn't make that move
