Modding mechanics of notification area, unlocking and system color?

I would really like to upgrade (currently 4.4.4) but I remember from the last time I tried Lollipop that it has this impractical UI design where you have to swipe down twice to get to the full options of the notification area and also "unlock twice" if you set e.g. a pattern lock.

Is there any ROM or tweak that lets you have "single swipe/unlock" even in current ROMs?

I also hate the cyan system color, so ideally, I'd also like to change that but that's really a nice to have, not essential like the things I just mentioned...
