Right now is the wrong time to implement something like this. It will destroy a lot of value and part of our market cap. It will destroy trust in our blockchain and it will portray us as untrustworthy and unstable - a history of making huge changes to the rules is not a favorable record for an asset that tries to promote itself on the merits of stability.
Implementing a reverse-peg can be done only when the market value is close to the value that is going to be artificially forced on it. Otherwise you will create a huge market swing. That wouldn't be good for our reputation or valuation.
So it might be a good idea at the right time, but it's a very bad idea right now.
