If 750W is about 1HP.
A 1500W spindle is 2HP.
Now the important questions about the spindle are:
1. At what RPM is maximum mechanical power output? Does the motor driver effect that?
2. Is that RPM a good match for the feed rates these NEMA23 steppers can deliver and honestly the answer in all 3 cases is likely no.
So the quality of cut and the tool life will diminish. Though obviously the results can always be good enough and someone could always get more tools.

Another key aspect I failed to mention was the frame construction, which impacts pretty much everything. Routers are a complicated thing.
There's also a major difference between using a standard woodworking router or an industrial spindle. The
ShopBot FAQ has a good explanation of this.
