Who should be the next Galactic Legend after Ahsoka Tano?

That's Mitth'raw'nuruodo to you

And the event could be called 'Heir to the Empire'

I still think Maul should be Ahsoka's GL counter

If you've noticed with all the GLs (dark side and light side), they've met each other:
-Rey and Kylo Ren meet several times throughout the Sequel Trilogy
-Luke and Palpatine met on the Second Death Star
-Obi-Wan and Anakin were really close during the Clone Wars
-Leia and Jabba met on Tatooine when rescuing Han Solo
