Federal Consolidation/ ECLRP

Hoping to get help understanding consolidation of federal student loans. I am working on joining the Air Force which has ECLRP (enlisted college repayment program). They will pay up to 65k of qualifying student loans.

I have 5 subsidized and 4 unsubsidized. I then have 4 Perkins loans. A requirement for ECLRP is to consolidate the loans. Initially I was going to pay off the Perkins but it looks like I can consolidate the Perkins with the rest. Is there any issue with consolidating Perkins loans with the sub / unsub? Or anything to consider? I’m not sure why they’re separated in the first place. I pay sub/unsub through one portal and the perkins via another.

Basically where I’m at is why pay off the Perkins right away if I can get them consolidated for the ECLRP?

Thanks to anyone for help!
