This is for creating New Mega Pokemon for Pokemon with no Mega forms currently.
For the first I was thinking about one for Golurk.
I was thinking maybe his mega can be based on Golurk's ability to Fly without being a Flying Type or having the ability Levitate, yet also basing off his tankish power.
I was thinking for starter it can change from Ghost/Ground to either Ghost/Flying or Flying/Ground, then maybe what if it got extra Arms (maybe a total of 6 I was thinking it would look cool with arms like this [http://fc08.deviantart.net/fs71/f/2012/184/a/e/asura_the_destructor_by_putleadinurhead-d55wbds.jpg] maybe). Had Iron Fist ability still, and is Attack, Defense, and Speed got a bit of an increase.
