Okay. Why I say giving Sombra more damage and/or reduced spread is because shes a ghost.

Without changes to her stealth and translator shes basically an unpunishable flanker with a guaranteed escape mechanism. Nothing stopping her from dismantling your backline before they have time to do anything. Pair that woth Tracer and I promise you wouldnt hear the end of Tracer/Sombra dive.

The rest of your suggestions dont make sense to me. At best Hack puts you on Sombras level. Pure shooter mechanics, she doesnt have an ability to damage you and now you dont have one to damage her. EMP can be outplayed with map geometry and is in no way “oppressive”.
