Not without substantial modification.  The Stag input shaft is much longer.

And even with the right gear set, I wouldn't expect it to last for very long.  The Stag also has a much thicker case (especially
around the mounting flange and bellhousing) and Torrington bearings instead of thrust washers on the countershaft.
