I take it you'll have changed the whole management. I'd leave it and think about just making a neat job of routing your leads. The coil packs from fords are v.expensive and they do fail giving you a nasty misfire. Am sure if you was determined there is a way of converting but also feel you'd be creating alot more problems than you would solve.
Seem to remember when one of my coils went up the swanny it was about £90 and thats cheap because I have a friend working for ford.
