You could get too much output in comparison. The bridge pickups are made to be higher output and have more bass than the neck model, as the sting movement at the bridge is smaller, so they are made to compensate. Using the bridge in the neck could then overdo those.
I am not saying that it can not work, not at all, but I would personally be more comfortable with putting a neck PU in the bridge than the other way around most of the time (I might try my MQ neck in the bridge one day with a PAF in the neck, cause then the output could still work nicely).
If you are quick with a soldering iron there is no real harm in trying it out, but generally I would say to trust in BKP and go the common route. They know what they are making and rarely should be overruled in their knowledge.
Btw, great PU choice. Those Stormies and PGs are incredible and underrated.
