I set up our WDH that way on our 2016 FWD Highlander and we've had no issues. IMO, unibody concerns aside, it's more important to follow that wheel well height advice with a FWD vehicle than a RWD vehicle. The front drive train is designed for a certain about of suspension "sink" and exceeding that could cause too much pressure on the CV joints.
I think you're safe with a WDH on a unibody if you're not exceeding the tow ratings AND you don't oversize the WDH. A 1000/10000 WDH will have a lot less flex than a 600/6000, which means a lot more stress on the body panels.
