The Brexit-backing businessman proposes meeting with club members to discuss plans to replace "a committee of well-intentioned amateurs"
Arron Bank wants to bring down the Gloucestershire hierarchy and prevent the club from existing "only in cricket's history book".
Members have been invited to his home on June 4 to discuss his plans to overhaul the club which he claims is in a "downward spiral, in "managed decline" and "poor shape" financially.
Last month saw David Jones removed as club chair and losses of £1.2 million was confirmed for the last year.
On Thursday (May 16), it was announced that acting chair Steve Nelson and Rebecca Watkin, the honorary treasurer, will step down from the executive board at the end of the season after five-year terms.

Banks founded the pro-Brexit campaign group Leave.EU and loaned them £8 million for the 2016 EU referendum. In a profile published in the same year, he was described by The New Statesman as "the man who bought Brexit".
His business background is focused on insurance. One former company, Brightside Group, were the naming sponsor of the County Ground and another sponsored Somerset during the T20 Blast.
The current chair of Thornbury Cricket Club claims to have been a Gloucestershire supporter for "many years" and has a long-term vision for the club comprising three objectives.
They include building a new home ground (the club have already outlined plans to leave Nevil Road); winning the County Championship for the first time; and hosting a Test at the new venue.

He has identified a "suitable" new chair and is open to changing the ownership model to incorporate third-party investment and members.
The letter, sent to members and uploaded via his X account, also includes his vision for the future of the Championship while incorrectly citing the "17 sides" which play the competition.
Subsequent posts on X made reference to "GLEXIT", the ECB being taken over by a "woke, diversity, inclusion and equality cult" and that "country cricket has been left to rot".
In response to the letter, a Gloucestershire statement to The Daily Telegraph read: "As a prominent sports club we regularly have local businesses and business people reach out to us from across a range of industries and backgrounds and it's standard practice and good governance for us to meet with them to hear their thoughts and views."
