I have been trying to figure out a way to re-bark my very old, very neglected pear tree. I came upon the idea to use some of the suckers coming up near the trunk as "bridges". Would it be possible to attach some of the suckers to the main trunk, where the barks has been removed, and have them eventually grow into the remaining bark?

I had though of actually grafting some sprouts near the roots, but there are some suckers already coming up about 4 inches away. Is this just way too out there or could it work over time?
