Personally, I think you'll have more success with something more gradual than a complete syntactic overhaul. I've never used pure4j or frege but it sounds like pure4j is something you could try out incrementally, which could be quite immediately useful for your team.

Best of luck!

The idea behind both would be to introduce it incrementally, carving out parts of the codebase to be rewritten one section at a time.

You're right, though; pure4j offers an immediate and easily obtainable win, so it'd definitely be an easier pill to swallow. Thanks :)
