Would i be able to wire a potentiometer to 1 Arduino nano, then using a bluetooth module transmit that pot's signal to another arduino nano to limit a connection?
Like Delta_G said, definitely. Arduinos would be well-suited for this.
You can use the ADC to determine the output of the pot, and send the data over the air to another Arduino that has a digitally controlled pot where the micro can tell it what to do. Pretty straight forward stuff.
I don't know what resistance range you need, but SparkFun sells this 10k digital pot for $1.50.
