A/C & Heater Blower Output

[AP9]

Is it possible to increase the volumetric output of the HVAC system? For example, aftermarket blowers or increased voltage into stock blower motor?

I was reading through some old threads and they mostly seem to address the replacement of a bad blower resistor. There's nothing wrong with mine, just that I'd like to have a higher air flow rate at the highest fan speed.

I have never heard of anyone trying that. Maybe look up blowers from bigger Ford trucks and SUVs that have to cool or heat a larger cab and see if they fit.
