Light Box and Flat Bed Trucks (Request)

I know, i’ve read the FAQ’s etc. etc. about open-wheelers and trucks and stuff, but I have a questions about possible light box and flatbed trucks. Since there is a semi-truck monocoque available is it possible (and is someone willing) to make light box trucks like these?

IMHO: they are all based on pick-ups and panel vans, it would extend the game to making it possible to produce highly utilitarian vehicles.
