[Q] Best ROM for most RAM?

Hy guys,

I play Pokémon Go a LOT.
And I am facing issues with Ram.
Usually I run these apps at the same time, while playing:

-Pokémon Go (the game itself)
-Google Maps (To navigate to some exact addresses)
-A Pokémon map (To get some hints :3)
-Poweramp (Music playing App)
-IV Calculator (to know if I got a decent Pokémon or not)
-Toolbox (to know type advantages when fighting gyms)

And I think that is all i run...
That takes up about 1.5-1.6GB Ram.

What do i need?
1.6GB+ Free Ram
Multiboot (wanna run it as a secondary Rom)
Aosp or touchwiz or ANYTHING else... doesn't matter

Any suggestion? :)
