I agree with your point. I think with the crowdfunding route having a CTO is crucial. Like DevX mentioned, after raising money I would be able to find someone who is compatible and has a good track record to fill that position.
I would love to launch the commercial and home versions simultaneously. However, the components need to be different for the commercial version because the product needs to be more robust. Therefore you're essentially designing, building, and shipping two different products. It makes things more risky, but there is a possibility to make it work if the same body component (which is an aluminum extruded frame with embedded track rails)can be used for both machines.
