Would everyone be against using Mustang II disc brakes?

Hey all,
As some know, I am trying to gather ideas and put together some different aftermarket products for the Mopar crowd. I am looking into a tubular Kmember, and a friend mentioned how cheap all of the Mustang stuff was. If I put together a complete kit, with EVERYTHING including Kmember, lower control arm, spindles, disc brakes, etc...and it used Mustang II components, would the die hards kill me for putting a Mustang part on a Mopar?
It seems the most logical way to keep the cost down as it seems every company sells products for the Mustang II spindles.
How many would frown on this, and how many would be okay with it? Complete disc brake sets can be had for less than $300 for the Mustang II spindles, although I would probably let the customer buy their own brake setup, as the options are endless.
I am just trying to put some prices together to see how cheap I could make these units. Let me know your opinions...
Thanks in advance!
