Halo universe expansion idea

Just thought it would be cool if Microsoft did expand the halo universe to have other companies other than 343 to tackle different games for halo, now I know we’re getting it with certain affinity and we have halo wars and to smaller extent spartan assault. Let’s say they do what riot is doing with league of legends and why not expand halos story into different game genres and just have the universe connected through different games instead of all in one. There is a bunch of halo material out there to create so many stories, maybe a MMORPG or Mobile game, a card game and have some smaller developers work on these games this way 343 is still only in charge of infinite and it’s future and at the same time expand halo to more people with different style of halo games but at the same time all in the same universe to have crossover events. Is this something Microsoft should consider?
