And the op by, just buying a "normal" bike, would then have a bike that stood on the shoulders of the millions of "normal" bikes that came before it.

But by choosing to design an uncommon geometry the Op is taking on the task of ploughing that field for the first time. Not that there's anything wrong about this. This is how discoveries are made, for better or worse. But i do take issue with the OP taking issue with others expressing their questions, that they're not "allowed" to ask. Whether the Op's design has any merit or benefit is now off the table. So the Op asked for advise, but only the positive kind. Not in this forum.
