Merging tuning packs? Battle Corpses + Enhanced Gameplay mods? Please help me combine them

Hi! i always play with the enhanced gameplay mod (stronger but more expensive walls, some seige units can go on walls, unique units are stronger) and really want to use the BATTLE CORPSES MOD (bodies stay visible for 5min after dying).

is there an easy way to merge two tuning packs? Can I somehow open up the enchanced gameplay tuning pack and just choose some option in there or paste some code to make bodies stay dead for a few min?
