This may or may not be to your tastes, but I've just set up a p2pool node which automatically converts merged coins into devcoins (because of it's relatively stable price), and pays them out to a registered bitcoin-devcoin address pair. You use the bitcoin address as your username to connect and it does the rest.
http://blisteringpool.com has all the info. It's a 1% fee, but you get all the devcoins that were received from merge mining, plus a 0.2% bonus payout in devcoins, which is converted from the merged coins. I'll increase this as the pool hashrate increases.
EDIT: also paying out 10,000 devcoins minimum daily as the bonus payout, split by hashpower.
