Either fulfill the details of the silver coin plan, or use the funds to top up the supernode bounty fund and add a tapering period where the reward reduces gradually over 12 months, to prevent the supernode system ending abruptly with a catastrophic drop in supernode numbers. All the coins locked up in supernodes getting liquidated at the same time could be a coin killing event.
That's exactly what I'd do too but such boldness and sense rarely goes down well with the people with the plan, or lack thereof.
