As the is no Debian MariaDB package in Wheezy I don't see this as being a priority for TKL devs.
On the other hand, if someone wanted to develop one (perhaps using the upstream repo?) then perhaps it would make it to release prior to Jessie based TKL...
I doubt we will see a TKL LAMP with MariaDB until Jessie is out
