The only way that will work is liquidation.
Start afresh, make it theirs from the bottom up. That will however require short/medium term pain for long term 'gain.'
Disclaimer: 'Gain' refers to the existence of a Portsmouth football club in the football league, not a european or premiership force, just a nationally competing club under their control. And even then, only after a decade of fightback. And no, they'll never go for that; They want it all and they want it now!!
