yes you can pool but you cannot share what you get, f.e. potions aren't transferable, so you cannot share them with the member of your pool. So one have the potions to open all packs and other have packs without potions.
Also it is a question of trust to make a pool as in the end the account-owner can just keep all and sent you nothing.
So I think it would be much easier to just allow to buy small packages.

Nice for you, but not everybody can buy 25k packs ...

If you are so well, why you can't get others a upvote instead of yourself ?
I mean it is not that I beg for votes but to reply and give only a upvote to your reply show me what guy you are - sorry to say this.
