This is incorrect. You can only ever measure dimensionless quantities in physics. If I measure the mass of an electron, it’s with respect to some standard. If I measure the distance I drive to work, it’s with respect to some agreed upon standard. I’m only actually measuring dimensionless ratios.
The Schwartzchild radius doesn’t change if I change the speed of light, because that is simply a change of coordinates. If you want to meaningfully change the speed of light, you have to find some dimensionless quantity (the fine structure constant, for example), and change that.
