Yes I wanted to show how much power is in this small processor when the program is optimized well.

with this statement you suggest the we should step back and stay with F4? Or the UHSDR is not properly optimized? Believe me or not it is at the best level we can... Anyway, it's your choice to use the UHSDR or not. Beside the intention of suggestion is positive or not, DDC/DUC is a concept where is NO local oscillator!
@Andreas: 2MSPS for one ADC, ~4MSPS for two and 6MSPS for 3 in interleaved mode. But all then stucks at the 12 bit resolution and ADC dynamic... I've tried high bin count FFT (large processing gain) and the high input noise causes that the MDS is at the level of ~-70dBFS.
