Do it man. I've had mine for about the same time, but I've done the opposite to you. I've got a wrr and recently unlocked a whole new bike. I've now got 2 bikes now for the price of just over one...
But my god, I went for my first ride with it now as a Supermoto, and wow I love it. If you have the cash, keep both wheelsets, like I have. It took me nearly 6 months to finally put my SM wheelset together, as I live in Australia, and had to order my wheels from USA. Then finding tyres to put on it, all the while conducting repairs from riding vigorously offroad. But trust me the wait was worth it. And I think you'll really enjoy having the diversity, and opening up a new world offroad.
