A p2pool node might help you...basic guide here:
https://bitcointalk.org/index.php?topic=62842.0You'd have to set up all the daemons and all that, and as long as you're using the same chain type you wouldn't have to change your miner settings (eg SHA vs Scypt). Once you've got p2pool working and the miners connect, changing what you mine is as simple as restarting the p2pool node with the correct port/username/password for the daemon you want to mine. I haven't tested this with Scrypt, only with sha256 and ended up setting up merged mining on my pool
