Threaded hose tails are easily sourced in all sizes.
Will take the fairing off over the weekend and check the layout.
If you're able to make somewhat-involved mods to the stock housing, basically all you have to do is add another port near the temp sender for the bypass line. If you could weld up some extra material, then drill and tap a spot for a hose barb, that should work.

As I mentioned in the previous post, the extra flow to the stat might make the stock temperature less than ideal, so you may want to try to find a hotter stat to fit the stock housing.
