Applying a texture to the missing parts of models?

Some models don't have backs to them because they're never visible except in gmod.
This produces unsightly visual errors, such as above.
Is it possible using the new render functions to draw a plain plane across the gaps to provide a fake back?

Dear lord this is an amazing idea. I hate when I find the perfect prop the make something with and realize it's got that see-through center! :argh:

Could you just use render.DrawQuadEasy with a texture of vgui/white and draw over the back?
