I'd like to understand more about your motor selection and what makes you confident it's not the limiting factor. Your blower looks amazing, I could see that thing churning out a ton of air.
Another poster mentioned the Matthias Wandel video and he uses a tachomoter to measure the blade RPM. You should consider doing that to see what RPM your blades are actually getting to. He also uses a anemometer to measure the effective airflow to compare.
I'm relatively convinced if you increase the power going into the blower you can achieve the flow you need.
Read up on your circle area calculation. Some devices measure in square feet for the area and some in square inches. I never thought I would have to use math again until I got into woodworking...

This is the one I use when I setup my DC. I think it was sold under a differnet name but looks the exact same. Let me know if you need help.
