Anyone offer engine swap packages for 05/06 Mustang?

I know you can buy 3-valve engines from a few different dealers, but I have not noticed any ads for swaps. If someone was interested in upgrading a V-6 car to a V-8 it would take a lot more than just an engine swap. The rear would need to be changed out to the 8.8" type, the pcm would have to be replaced, the gauge cluster would give the wrong rpm reading, the transmission would have to be upgraded to a 3650 from the t-5 (if manual) and there are many wiring harness issues just to name a few hurdles.
