Question Is Zante to Athens via South Peloponnese in 10 Days Doable?

I'm in the middle of planning a trip and really want to explore the Peloponnese region. The problem is, flights into Kalamata are not working out for us, so we're considering starting in Zante and making our way to Athens via the south of Peloponnese over 10 days. I'm wondering if this is a realistic plan? Has anyone done a similar route? I'm curious about the travel times between places, must-see stops along the way, and if 10 days is enough to enjoy it without rushing too much. Any advice or insights would be super helpful!
