Here's a really near-perfect rendition of the Range Rover Velar in a pickup form. It appears to have a shortened wheelbase, but with sporty build and full-offroad appearance especially with the tyres.

That's just for the Velar. For the Range Rover Vogue, a 6x6 pickup version was released by Auto company T.Fotiadis Design.
Both appear to be really sleek, however weird-looking.
