I quickly found that F'Size is not static when F is a type used in a generic instantiation so the following does not work.
type Modular is mod 2**F'Size;
I then realized that the idea of using a packed Boolean array does not lend itself to easily transform the floating point magic number calculation to a packed Boolean array and then I would also have to deal with the subtraction as well as the shift. So, this is also a non-starter.
