Sure it is "possible", since it obviously had been done before somehow...
The question is whether it is sensible. The overall structure is much
simpler now, we use less code for the same functionality. And we basically
do what TeX does.

You could type the x first and delete the y afterwards:
x+|y^{2} -> x+x|y^{2} -> x+x^{2}
But even your prefered way could be used if we had empty blue boxes to mark
empty bases.
