To my inexperienced eye, rolling in a new timing chain seems easier than messing with taking the cam sprocket off and installing a woodruff key, not to mention messing with drip timing on the IP.
Thoughts? Advice?
Thanks.

Sorry but I don't follow your logic. Are you trying to avoid drip timing an IP by putting in a new chain? You should really check begin of delivery after replacing the chain.
Do you have access to the factory service manual (FSM)? Chapter 05-320 is your man!
If you want to correct for chain elongation then I'd go for the offset key - although I don't think I'd bother for 4 degrees => from my calculations the MB key is a bit out at the lower degrees of elongation
OM617 (non turbo) cam profile specs, piston height specs etc
I think an offset of 0.49mm is required not 0.7mm - but anyway there's nothing you as a DIY mechanic can do about that discrepancy => you can only choose to use the key or not.
