shag- well, if there is a WAF, and he dont like the BIG M80's, have you maybe tried to lean him towards a bookshelf, like a M22's, and maybe some QS4's? those are MUCH smaller, and they could be mounted very nicely with the FMB's. and he could get an awesome receiver, the best SVS or HSU sub he could want, and stil come WAY under the $4K that the lifestyle system would cost. heck, he could even get everything in custom finishes to appease the WAF, and still be inder $4K.
just as a friend, i would seriously just point out other options avail to him before he goes and wastes that kind of money..
