I think the point of that approach is that yes, Rumple would want his power, but any use of it that influences Belle's feelings in a negative way would weaken his powers. So, the end result would be that Rumple would have to really learn how to control his powers, and control his dark selfish urges associated with the use of the power.

It might actually make Rumple the Dark One that is able to use the DO powers for good.
