This can be done fairly simply, though it will affect every edit until you remove the code. Should co-operate fine with your textarea script too.

I quite like the idea behind this though, so I've also drafted a script that adds a small icon beside the summary box, works using  (so no need to edit JS pages to change/disable the summary), allows changing the summary on multiple open tabs at once, and can set move/protect/delete reasons too.
