Lee - It can be done, I documented adding BH stepped attenuators based on the Mourquiet, to both a standard and an oversized panel (both custom, not stock BH). Believe Paul when he says it will be a tight fit, and my DIY versions didn't really save any $ over adapting a BH kit. Check out S.E.X. 2.1.1 and 3.0.1 posts here back in Jan/March.
If you really want them on the front of the kit you could build a base that would accommodate.(taller /longer)
Good Luck
