The only way I see for Mt Gox's revival to work is if they get their 100,000+ former users involved again.
A simple way to do that, is to keep track of how many "lost coins" everyone had (the "goxed" coins) and promise to replace them progressively with real BTC gained from the trading fees.
User's account would show their real and goxed BTC balances separately along with any other fiat or crypto currency.
The goxed coins would then be traded for real BTC, LTC, dogecoin, USD, etc and, trust me, there would be a market for those goxed coins - at the right price.
They'd be heavily discounted at first, like towards the end of the original Mt Gox, and they would gradually increase in value as people see them progressively getting replaced by real coins.
Some risk tolerant people could make a killing and others would gladly just recoup a fraction of their lost coins.
The new Mt Gox being a completely new company in a different country, backed and run by real capitalists, there would be no reason to associate it with the previous incompetent management.
