could always take the cheap option and use names and logos similar to real companies like die-cast toy cars often have
many of the formula sketch cars would give unreliable results in cfd in their current form due to low polygon counts
maybe the ex-competitors from formula sketch could set up their own site (obviously they could not judge the cars if they continue to compete) and run it the way they think is best, you know, for the people by the people.
a few more standard parameters might be a good idea as well (to stop overly small sidepods etc) and maybe standard engine/gearboxes/tubs if they are not already used.
