There are 2 matters regarding the causeways that I've not seen mentioned.
In 2014 it was announced that the causeway of G1 had been found in a village 33' below someone's house. G1's causeway is abruptly cut off at the cliff but it was estimated to be approx. 825m long continuing to the NE. Also, in 1990 Hawass announced the finding of G1's valley temple below a village.

This would upset your 4.6 degrees.

Egyptologists believe the causeways were covered, like a tube of sorts. I don't know why they think so, but IF that's true it would make operation of a funicular difficult, if not impossible.
