Bill G.:
If you're willing to sacrifice your existing stock then, yes, it'd be easier to whack off the pistol grip, fit up a long-tang triggerguard, do any tang-bending needed and THEN fit and bondo-up the old stock as a template to send to the duplicators.
I think a straight grip Fox is about the most attractive gun imagineable. I've done a couple of them now and have had to bend the tangs very little but did need to mill a little bit of metal off the bottem-end of the lower tang where it follows the contour of the pistol grip. How much tang-bending you do will depend on how the geometry works out to get the finished look and dimensions you want.
BTW I've also used Wenigs and been very happy with their work.
