Hi there! You most certainly can! Many people collect and carry a variety of different lens pairs for their interchangeable frames to accommodate different lighting conditions. One thing to keep in mind is that because the Valor is considered a safety rated frame, it therefore must meet certain impact and shatter resistance standards. For this reason, you may experience that a bit more effort is required to interchange than a non safety rated pair. Hope you found this helpful!
Frame width isn’t everything. I have owned multiple pairs of the Boss because I have a wide head, but I’ve never found them to be particularly comfortable. A HUGE hole in the Wiley X line is a wide Asian fit frame. I have high cheek bones and the Boss sits more on my cheek bones rather than the bridge of my nose. I’ve switched to the 7eye Panhead, the shorter lens height works a somewhat better for me, but I do wish the frame was a little wider.
