No.

I'd need to see the code which implements such an option, before I
express my opinion.

The behavior was changed in order to avoid huge line spacing when a
font reports a preposterously large height.  Any option such as the
one you are talking about will have to keep the new behavior whereby
the display engine doesn't user the font height for drawing the cursor
on empty lines, because this will have an even worse effects.

It's impossible to keep lines at the same spacing when multiple fonts
are involved anyway, so the situation you are describing is not new.
