Much of the reason people are asking for a roof rack is because the currently available solutions are not acceptable.
I myself find the Thule racks to be toadly fugly. They do not fit the aesthetics of the VX at all. (well, mebbe an Astral). And the Yakima Loadwarrior racks sit too high, are too expensive and slightly too large IMHO. Those are the only options we have.
I wish I had the skills and equip to post such a thread. "Making" parts is beyond my skillset and I applaud yours.
