Very sensible.  Include a rebate each side and the join won't need to be faired.  The glass on the skin is all that is required for the join as long as the overlap is sufficient and the laminate quality good (bagging is ideal).  The width of rebate should be 100 x the thickness of the laminate.  Assuming it is bagged, this is near enough 1mm per 100gsm.  ie, a 600 gsm laminate will be 0.6mm thick, so the rebate should be 0.5-1mm thick (too deep is better than too shallow, filling in the hollow is easier than fairing in the bulge) and 60mm wide.   This will look insufficient so you will probably double the laminate and the rebate dimensions.  In which case, make sure you taper the edges of the extra cloth by at least 10mm per side.
