Can you get a long shot of the hall? If you can I'll "paint" the door so you can see what it would look like. It wouldnt necessarily suck. Do you feel up to a fun faux finish? The white blotches are paint? or bleach? If they are bleach you could carefully paint stain in those areas to even out the colour. If they are paint they could be sanded back.

It's a very nice door, but I don't understand why it is so blotchy white. Can that be fixed? It would look great if it was just stained & varnished. No, I don't think it would look nice painted, either. Maybe you can sand past that blotchy stuff, whatever it is, and then re-stain, and varnish from there.
