I say you keep Peppers and make him situational, even if he needs to start to be happy (just guessing there). Helps pass rush and is solid in run even if coverage is on downside.

You keep Perry if you are optimistic about his shoulder, if not then keep Neal. This assumes each can be had for a modest 3 year deal.

I would actually prefer Guion as someone had his numbers being 20% better versus the run than Raji. You stick Guion and Pennell in and both guys can collapse the middle and both are taller than Raji so deflected passes might increase. But Guion, younger and more pass rush, might be more expensive. Raji as fall back is OK.

Then you need to find an ILB somewhere to allow Matthews to roam, mainly get out of coverage.

Bonus, find pass rushing OLB somewhere or find the key you lost to Mulumba last year. Mulumba should be an octopus like Neal out there.
