I'll be supporting it. As part of a wider set of changes to the Sov game it would be good to see it - or a derivative implemented. Then CCP can find something that isnt pos's for us to shoot at to switch sovereignity - thats the only way this guys idea falls down for me, it doesnt go far enough for a change suggestion, it still relies on the pos mechanic as the central part of sov holding.
Edit _ Pattern has suggested in various places, as has La Vista, that Sov is due for an update during the summer.
