The only issue on an Uno would be interrupt latency. If you disable all
other interrupts, latency should be easily low enough. The only real
advantage of going to ARM is interrupt priority. You could assign the
sampling interrupt to maximum priority without having to disable other
interrupts.

I would suggest starting with a more capable microcontroller. I like the $15
Adafruit ItsyBitsy M4 modules, which are programmable with the Arduino IDE, but
have a 120MHz clock, 32 bit timers, floating point hardware, and two 1Mhz 12bit
adc's. Their processor is an ATSAMD51 (Cortex M4). The original Uno is very
limited for precision timing.
