I’m sure lots of people can get excited by the idea in principle, but until there are plans there’s not a lot to be done.
Then it needs agreement by the club, and also by the Council as they hold the freehold of the land.
If everyone is in agreement then you can start thinking about how you finance such an initiative and decide to what extent fan involvement is needed. Crowdfunding, bonds and suchlike. The club have indicated it would need to be 100% financed by external (non club) sources.
Sounds like a horse before cart situation with the ‘no plan’ scenario.
