That's completely and thoroughly possible, and doesn't at all conflict with the way eBay operates. I'm not sure if users would accept it particularly readily though, there's other escrow services that require no trust in the escrow agent, why would they use Bitcoin? I'm not particularly opposed to the idea, I don't mind PayPal particularly, I'm just not sure how well it would be adopted.
