A logical idea, with a few drawbacks.

One of them would be getting up to the windows, a ladder seems to be the best option here or climbing would also do it. Another drawback would be once you are inside, that is if you can get in through the window. I would of thought that the windows would be magically sealed and un-breakable. Anyway, if you decided to jump down and get the sword you would most likely break your leg(s) or back with the fall. The ladder would also come in handy, but wouldn't look good for a quick escape as it would involve setting it up.

And also, wouldn't it be nicer to just stay in Hyrule. It is a nice place after all.
