I've never found GTA Online to be like a regular, story-mode GTA game exactly for that reason, there isn't anything special about starting over.

In GTA IV, for example, I LOVE replaying that game because of all the neat little things you pick up in the specific missions, and the way you see the protagonists character arc play out over the course of 50+ linear missions, and you literally CAN'T do that in GTA Online, since the story unfolds as YOU meet other players, not as the character does.

If you just want to delete them because you don't like their appearence, I'd suggest what Synth did, just make a second one. If you think starting over will change everything, it won't; for the reasons I gave, and from personal experience.
