No, you need two rims, the dynohub on the other wheel.
Do not overlook the cost of spokes, price can be quite variable. I have been quoted at local bike shops anything from $24 per wheel to $1.55 per spoke. My last build was with spokes that I got mail order, which unfortunately meant a bag of 50 spokes. So, I have 14 spare spokes per wheel.
