Additional clan perks and clan taxes

Greetings clashers,
I was just thinking about something like perks for clans which will cost materials to upgrade.
Based on this should be some changeable taxes which leader or co-leader can edit (0-50% for example). These taxes would be only from clan wars or even better from classic fights.
This feature will bring even more importance of clans and more communication and teamwork in clan.
Perks should be classified to different lvls of clan so you cant upgrade every perk on low lvl of clan.
It will bring even some functional hierarchy to EVERY clan and no more free nonsense 49 co-leaders in clan.

Just a bit from dirty corner of my brain ^.^

Thanks for reading and any reply.

I really dont understand this.
