Stock or near stock ROM topic

Long story short, I am rooted and s-on and running an older version of insertcoin rom. The TWRP backup of my stock rom won't restore and I want to use sunshine to s-off but it says I need to have a stock or close to stock rom. Can anyone recommend a rom that will work for me? Keep in mind that I'm still on firmware that is compatible with 4.4.3. I'm only needing the rom to enable me to s-off, then I can upgrade everything.
Thanks.
