Also, depending on the objects, one may consider a few other tagged objects, like perhaps None, True, and False

I doubt that it's worth it: they are not dynamically computed anyway, so there is little gain (only avoiding manipulating their refcounts), and the loss is a greater number of special cases when accessing contents of every object.

or even just use 31/63 bits for the tagged integer value, with a 1 in the lowest bit signifying it as a tagged integer.

This is exactly what my compiler of my language does.
