I started to put this together once and stopped for no real reason. I believe the first step would be to create typical profiles for each aircraft. For example, a B-25C could use takeoff, 5 minute formup, mil power climb to critical altitude, then outbound to a target at a some speed short of full power that allows you to maintain formation. Figure out combat radius with fuel burns of 1.0, 1.5, and 2.0 and then also max range within 60 minutes. For B-17s, perhaps choose 25,000 feet and a medium altitude. For fighters, air-to-air configurations at medium and high altitudes, and air-to-ground at medium altitudes with the different bomb loads available.
Easyscore had a table that was in the works when we used to run the Close Escort event, but it was incomplete. He was setting it up for CM planning purposes, so really, a resource such as the one you're describing Dogg would benefit both the players and the CMs.
