Transferring Coins Across Accounts

I'm not sure if this has been discussed before, but it comes around as I have switched from the .com version to the .co.uk version, but I still have 200 odd coins left which I wont be able to use as Ii no longer play on that version. I'm wondering about the phesability of a way to transfer coins as "gifts" to other accounts. This is done on many platforms such as steam, or on other mobile games such as 8 ball pool. It would be very beneficial and can also be used in a positive way, such as helping out friends who are just starting out, or Bday/Xxmas presents to your mates.
