Replace kitkat time date picker worth lollipop's

I searched but can't find if there's a way to fully replace the system time and date pickers in kitkat with the nicer lollipop spinner style picker (and please don't say update to lollipop, I've just downgraded!).
I have a rooted Xperia Z3 running 4.4.4.
I've checked xposed but can't seem to find a module in there either.
Thanks
