Can't see why it wouldn't work, for some time...however, the dust running by the motor will eventually get into it and ruin it, or, worse still, catch fire! Perhaps you could try clening the motor with compressed air every month or so, to stop the buildup of dust in the motor housing...That's what I would do in your position.
Another consideration is that wood dust is biodegradable, but fiberglass and plastic dust is not...
