My personal favorite ROMs to use are AICP and Slim. For nostalgia's sake, I'd love to see someone continue the Sorcery line of ROMs. It was my favorite to use on my Galaxy Nexus, mainly because of the a la cart additions for their proprietary add-ons as well as other helpful features, much like the Xposed depository. Unfortunately, they discontinued their development well before KitKat.
Although, any ROM I flash would need to include LTE and controller support. It's an absolute necessity for me. However, I understand that's a lot to ask.. As far as I know, I don't think the device tree has been released for the LTE version, so I'm not going to be holding my breath.
Truth be told, what I would appreciate most of all is a custom kernel that would allow me to undervolt and allow for discrete CPU frequencies that aren't linked to each other. The stock kernel only allows for the minimum and the maximum frequencies to be the same, so I can never get very good deep sleep/screen off battery life since the processor is always running at least 2 cores at 1500mhz.
I do appreciate the offer and it's people like you that remind me how great this community, and the Android community in general, truly is.
