The refactoring is a requirement for such thing - the goal of that
work is really to allow greater flexibility of legend widget. The plan
is to get it into 2.4 release.

Unfortunately I do not think it would be possible to have a plugin
that would show the proportional legend directly in legend widget or
composer legend. Maybe a plugin that would just generate an image with
proportional legend so it could be included in composition - not a
great solution.

I can imagine a python plugin for QGIS >=2.4 that would add this functionality.

I'm not really sure what you mean... maybe a screenshot would help.
