Max number of accounts

I have a total of 7 WoW accounts on my bnet account (5 "main" accounts and two used for RAF). I wanted to RAF 2 more accounts to level chars on my main accounts. However, there's an 8 games limit for a bnet account. I tried talking to a blizzard customer support representative, but he claims that he cannot remove games or move them to another bnet account.
The reason I want them on the same bnet account is the heirlooms, and while I can do it with RAF and guild bonus alone, I prefer to do it using as much XP bonus as I can get.
So obvious solution is create a new bnet account, and then either level without heirlooms (still pretty fast). Are there any other solutions?

You can move accounts between bnets. Find a different rep to talk to, ive done it several times without issue.

Can you post something I can take to them as proof that it can be done?
Screenshot a blizz mail (blackout personal details obviously) maybe?

You'll need to contact Billing, not sure CS has the ability. But they can most certainly move accounts to a new Battlenet. You should be able to get the two old RAF accounts moved to a new Battlenet to free up room for the new accounts.

2nd rep told me the same thing. He also said that europian and american accounts have different restrictions, and while this is possible for US accounts, it's not possible for europian ones.
Did anyone from europe manage to transfer wow accounts from one bnet account to another?
