Another thing that could be worth some experiments would be multiple
tagbits: We now use one bit to distinguish between pointers to objects
and ints. With 64 bit we could have much more tag bits and then
encode many objects in the way we now encode ints: 64 bits should
be enough to play with immediate points,  floats, chars... could be
interesting.
