Since it's a short rest, and you gain ki points every half hour, obviously you can just do it and no one will tell the Monk Commission on Fairness and Requirements (MCFR).
If you want to write a formal letter of non-compliance then please address it to the MCFR office of the Hall of Justice in Neverwinter.
This means that you can use a pole-arm if you don't also use the bow between short rests.

Also, everyone please let me know how long you want to rest before storming the fort.
