Okay, for some reason I thought you had your boat on a trailer/cradle in your driveway. Regardless, you make some valid points about keeping the hull and deck in the proper shape. I think it could be done (with the boat hauled, of course), but no doubt it would be a major undertaking.
Then again, what you are about to embark on is no picnic.
I would really think hard on the advice from Mainesail and others who've tried or seen this tried.
P.S. Also, you might touch base with ArtbyJody. He was facing some serious work on his Catalina 27 but eventually came to a different solution.
