I would add beware of the point estimates of average dried weight on websites. These are based on variable sample sizes and do not represent the range of a species. The specific gravity range numbers on that website begin to provide a hint on this. Some Hard Maples overlap with the lower ranges of Rosewoods.

As others have said, on average Hard Maple < European Sycamore or Red Maple < Bigleaf Maple (these are the most common maples used in guitars). Backs and rims can be thinned to compensate for inherent density, but there is a mechanical limit to that limits fully matching the weight (e.g., Cocobolo vs. one of the Maples).
