How to mutidirectionnal surface extrude ?

[texino84]

Hello, in SW2018, I have a patch that I would like to be extruded with respect to some inputed edges directionnal vectors (see picture). How to do it please?

(I tried basic extruded boss/base but it handle only one direction, "extruded surface" as well even though it's primarily designed for extruding a curve into a surface. I added lines to try "lofted boss" but as you can see on the second picture, the top splines end up not being "fully parallel"...)

 

In other words I'd like to map my orange surface so that it pass by all 4 endpoint of my vectors. Is it even feasible?
