Hmmm... nice approach. And clever use of spacebelow.

No, I don't think that would work. First of all, you'd need to keep
track of how many lines before the changed line were already wrapped, so
that you could know what line number to start with. So you'd have to
have already predetermined the relationships of the line starts to the
line numbers and either stored that somewhere and keep updating the
list; or work out the line starts each time.
Secondly, you'll need to trap some events in a frontscript and handle
things like inserting and deleting text, resizing the field/card, etc.
