Maybe a design contest is the way to progress things ?
Each team makes their own ideal designs together with full overview of weights and costs (both or parts and the whole lot) as well a sort analysis of building requirements (skill, tooling, etc)
We can then compare these designs to one-another and make the best of them the tue F12 ?
Or possible, combine a best idea's of a few designs into a new single F12 ?
Would that be an approach that the designers will be happy with ?
