how about one of these? they're relatively expensive but look like it would address your issue with minimal hose orientation problems:

Good choice. It's not that hard to do. Took maybe an hour because I didn't want to bugger it up. I suspect an experienced machinist could do it in less time.

This.
These thermostat housings are rotatable 360 degrees. There inexpensive, All over ebay and Amazon. Come in a variety of colors. But they need a little porting on the inside.
Note my temp switch.

I managed to get the sensor in the hole you are claiming is unusable. The L98 heads on the zz4 are threaded for a 3/8 NPT. So the best thing to do if you cannot use the intake is to turn the sensor down to fit a 3/8 npt thread.
