This post of yours Will...has inspired me. I have a lilac I am contemplating ROR. My intentions this spring...is to do it in ground. And leave it there...I'm still uncertain about it. So this will be great. If I like the years under its belt in ground I can bring it into a pot...OR...just leave as is if it's lost my inspiration. It was a tree purchased when my eyes were new on bonsai and I didn't grasp now all material should be bonsai. So...worse case I get new landscape matieral that looks cool.
