You simply dual boot your cyanogmod and stock your touchwiz.

Buy 2 galaxy s7

Its better the stock android if the phone has company developed apps that require expecific hardware. I changed from Sony stock 4.2 to CM 13 and i miss Xperia Music (Walkman)

Buy a nexus or oneplus.

>Exynos
>CM, AOSP ROMs
It's just not going to happen. Samsung doesn't release kernel source codes for the Exynos SoCs and both the S6 and the S7 have a locked bootloader.

not op but can you dualboot on the oneplus 3?

Yes, there is an unofficial multirom on xda forums.

You can do it with nexus phones and S4, which are officaly supported by multirom. but I don't think there's official build for even s6, so don't even think about cyanogenmod
Enjoy your iPhone with android.
