If I simply take the wire from the GEN terminal on the regulator, and move it over to the BAT terminal on the regulator, will that effectively bypass the regulator?

YES that by passes the Cutout Relay portion of the Voltage Regulator (its between BAT and GEN). If you do that the hot ungrounded battery feed via the ammeter which is present on the BAT terminal, is then connected to whatever you then connect that terminal to, such as say the output of an alternator...........

DONT FORGET MOST ALTERNATORS ARE FOR NEG GROUND so if the tractor were at Pos Ground??? you would have to swap ammeter leads or it will register bass ackwards

If a tractor has a coil ignition and you changed polarity, the coil leads would also need swapped HOWEVER if youre already at neg ground (like on most 12 volt tractors) neither of the above swaps are necessary
