You seem to have put off cleaning this up for way too long.
You should be able to register the same ssh pubkey with all the accounts.
Then just back up that pub and privkey on a usb stick somewhere and accesss everything from the same keypair.

One is, if an identify is ever compromised you can revoke it without loosing as much downtime (one device is compromised - just revoke that key - you now still have access on other devices) if you don't do this, you'd have to revoke the one key you use, which means you have to repeat the pain of copying identities between devices again.
