How to get JL 3-ways into an 03 mustang?

I was sitting in the car the otherday, obsolutely hating the qforms.  And came up with the idea, to leave my 6.5" woofers in the stock location, and put the 4" mid and tweeter in the map pocket on the door panels.  I think I am pretty much just make a little face plate and screw it right to the door panel.  Drill some holes and they are done.  I can probably even put the crossover inside the map pocket.  The angle even looks good for imaging, and would clear my leg and passenger legs.
