it is possible with the P3P but at what cost. There would be high chance of quality loss due to processing and compressing to keep under the max data rate the P3P supports. It may enable aliasing just to keep up with 120fps. But what good is super slow motion aerial?
I doubt there will be much demand for it, but support for higher fps (even if at a lower resolution) would be cool. It would be useful for me when recording rocket launches. And flying sequences get a neat, dreamy effect in slow motion.
I sometimes slow the video from my P2V down to twice the recorded duration. It usually does not look good, though.
