I very much doubt it without a major re-write of the quotes code - which is one of the more complex areas of phpBB (mainly down to historical reasons). The best you could hope for is that something may be possible when/if the quotes code is adapted to work with a WYSIWYG editor.
Might be an idea to post it in the Ideas forum.
