I wish all of you the best!
I don’t think this proposal system is a good plan, however. Product design by committee is a doomed idea. People in groups generally only actively commit support to things that are very much like things they already know and understand: things that already exist.
That falls apart when building entirely new things that haven’t existed before.
I hope you can make it work; I have no doubts about you guys, but the system you seem to be attempting to work within will probably not sustain innovation. Maybe along the way you will find a better way.
Either way, I wish you well and the best of luck. :)
