Default [Q] PURE AOSP (Or the closest solution)

Hi guys, this is my first post.
Btw I'm going to buy a G2 soon and I was interested to find a pure stock AOSP rom, or the closest one, after doing some searches in the forum I found the Nexus 5 GPE rom, and people's saying that it's bugged and heats the phone.
I like all the G2 specs so I'm definitively not going to buy a Nexus, the only thing I don't like of the G2 is the LG stock firmware so is there any port of pure AOSP without addons?
