Has anyone driven from Athens to Zurich via the longer land route?

Considering taking a trip and driving from Athens to Zurich over a period of maybe 7-8 days. I've been to Italy many times so wanted to take the route up through Slovenia, Macedonia, Serbia etc. Just wondering if anyone has done this and what difficulties they had if any? Would be in a rental car, flying into athens from Ireland and out of Zurich.

Any tips/recommendations welcome!
