Richard - I think you have made a fine choice is sticking with the stm32f4. It makes the project manageable for you, as you recent progress has shown.
Thank you for re-releasing under the TAPR lcense. Sure, love to have one :-) Glen - the optimisation for 700D has already been done by Don. No sign of any CPU limit. I had the same experience when I ported FreeDV 1600 to the stm32f4. A more modern stm32 variant is a "nice to have", but by no means essential.
