AOSP Notification Drawer?

Now that I have my G4 (TMo) rooted, unlocked, xposed, etc, I find I'm happy with pretty much everything. App Ops is built in, settings that were gone in stock can be easily added back with xposed modules, I'm no longer stuck with the crappy built-in battery monitor, bloat's been removed, etc. However, there is still one sticking point... I HATE the stock LG notification drawer, particularly its "quick settings" implementation, and would like to get this back to stock-style AOSP Lollipop. I had hoped to find a Xposed module to help with this, but nothing thusfar has been able to change the notification drawer. Custom ROMs are a potential option, but I'm pretty sure I'd hate the phone even more if I didn't have double-tap-to-wake, and I'd rather not compromise the camera quality.

Has anyone found a way to change this, or could point me in the right direction of figuring it out myself? (I suspect it may require a mod to the ROM.)
