Converting front exit cable shifter to rear

I would really like the idea of a rear exit cable but it seems like mounting is only half the problem to me. If you think about the actual cable operation it is a push/pull system. the cable is fully extended for park and fully retracted for 1st at the transmission lever. (I think) so if you reversed the entry to the transmission only, your cable would need to be opposite to operate. Like fully extended for 1st and fully retracted for park. so when you grabbed the shifter lever inside it would be in 1st in park and park in 1st... You'd need to either reverse the gate plate in the shifter or also change the geometry/cable routing at the shifter to match the trans.

I have a front exit hurst quarter stick that I protected the cable by getting about 1.5' of 6AN high heat tubing and slicing it down the side for a sheath over the cable, I then wrapped that in high temp reflective tape. It literally sits right against my header and so far so good at 1000 mi.
