Suggestion: Clan Wars ZP betting?

Okay, here's my idea:
What if we could bet some ZP in clan wars?

How would it work:
I thought about it for a little and what we could do is, deposit ZP in your clan bank.
Then clans would have two banks: one for betting, one called a "safe".
Of course I didn't think of it long enough to come up with a miraculous way of making this functional, but I'm sure with some brain storming there could be a safe and easy way to make this idea work.

What would it bring to the game?
More challenge, more fun.
Getting the players to push themselves in clan matches for an actual reward in question.

The only inconvenient I thought of would be ZP transfering.
If someone with two accounts and two clan just played against himself to transfer some ZP.

But yeah, I just thought I'd throw it out there and see what people think.
What do you think?
