Nearly impossible, as the high-end would require you to get an measure of the black hole once it reacts to Bowser presence. And by then, Bowser's disappeared.

Due to it being so high in Large Star, however, its high-end would easily be within the constraints of Solar System, and possibly even Multi-Solar System.
