I'm new CM12.1 Nightly ROM to CM Remix SM-N910T Note 4

Hi everyone I'm new to the forum and also new to android. I've been a iPhone user since the iPhone 3G & decided to get myself a Samsung Galaxy Note 4 SM-N910T (T-Mobile). I am currently running CM12.1 nightly ROM using TWRP recovery. I was looking around and found the CM Remix ROM & I'm itching to get my hands on it. I'm a noob when it come to android and to custom ROMs, but managed to get my phone rooted and flashed a custom ROM without turning my phone into a paperweight. So I'm trying to get a little direction and some know how to get CM Remix ROM with lollipop or maybe the new marshmallow. I really like CM12.1 nightly but I'm wanting all the extra tweaks and performance. So is it possible to flash the CM Remix ROM if I'm using CM12.1 NIGHTLY ROM currently? If so what files would I need. My build is CM-trltetmo 5.1.1 kernel version 3.10.40-gef59855 build CyanogenMod #1. I also just flashed the current version of CM12.1 nightly today (Oct. 27 2015). Any help would be appreciated. Thank you.
