Has Anyone Ever Given Their Players The Construction Rules In A Mecha Game?

So the bug to run, or at least work how the details on how to run, a Virtual Mekton game in GURPS. Virtual Mekton for those who don't know is a fan setting for the very old Mekton Zeta RPG that applied the Yu-Gi-Oh Serious Business formula to piloting Mechs in online multiplayer, and allowed players to customize their Mechs.

As GURPS Mecha is naturally one of my options for actually designing the Mechs I need to know people experiences with it, particularly with the construction rules in players hands.
