Hi guys! I'm new in the XDA and this is my first post. I'm a owner of a SGS 5 and I'm wondering replace the touchwiz in the actual rom of it (5.0) for the new Touchwiz from Galaxy S6, witch is more lighter than the actual. So I'm ask for the community of xda if that's possible or not and if not where are the alternatives to turn the actual rom of the S5 to looks more like pure android.

Sorry about my English
Thanks to all
