Very nice model. I think it can work nicely like this. Even when all supply is released. Slowly and gradually of course.

And this:

I also love the idea of collabing with other tokens and projects.

This will be golden nut of HIVE blockchain once everyone understand this is one of the most powerful (long term) features of a blockchain. ALL projects are automatically connected permissionled, as opposed with other technologies where authorization and permission is required first and then you still need to connect things up for them to work, on BOTH sides.

Other ideas could be use of WOO listed NFTs from other games, as a slightly modifier to the wealth won in a match for example. Representing an increase of the "popularity" of WOO in the HIVE blockchain and therefore also increasing (or at least maintaining) volume of WOO in the long run.
