Uh, of course you can make such a polyhedron.  Consider the
Egyptian and Mayan pyramids as examples of 5-sided polyhedron
(four triangles on the sides and a square on the bottom).
Adjusting the steepness of the sides can make it as fair
or unfair as you'd want.

Sure, they're not regular polyhedra, but neither is the d30 you spoke of.
