That's a fighter who does thief stuff, not a rogue who does fighter stuff. Building a character around sneak attack and skill expertise is pretty different than building one around multiple attacks and action surge.Well here you go, do not reinvent the wheel:
-Make any sort of Dex Fighter.
-Give him the criminal Background. *
-Give him stealth if you want to. Give him appropriate feats.
(Read this one up it is one of the best Backgrounds and certainly the most versatile, it allows a Party to go without a rogue and still do all the rogue things.)
For a lot of concepts, you want the good parts of the rogue mechanics without the unnecessary thief flavor.
