I've thought about this too and I have too much time invested to redo things in blogger, though I thought about it. (Also, there's the issue of not having the content be on your own server too, so if something happens to blogger...) But I'm using it for new stuff because it's just so much easier.
FWIW, I reference your site a lot, especially the regency and 18th century stuff, for your construction notes. So I definitely hope you won't take it down! :-)
