Referring to your PDF drawings,
Vl = fx * Vx + fz * Vz
Where fx = X/L and fz = Z/L
This would eliminate the conditionals you deal with while deciding whether it is a steep or shallow ramp.
In the ramp extremes it degenerates to Vl = Vx or Vl = Vz.
It looks intriguing, however, it leads to speeds which are too high:
Take the example from my paper with X=8, Z=2, Vx=4, Vz=3.
Your formula yields Vl=4.6
If I project this on the X-direction I get 4.4, which is too much as 4 is the maximum.
