aset, with its current specification, cannot do this
because there is no way to replace the old string (as a Lisp object)
with a new string.
Currently a string object points to a separate string text. That enables
aset to replace the old string text with a new string text.
If we wanted to change the string representation, that might become
impossible. That might cause problems in places that uses aset.
I propose srep because some of those places might use srep instead.
