I would try to launder it, buy some (virtual) stuff and the sell it back/use it. One thing you could do is to use an 3rd party company that transfers your Paypal money to another virtual wallet (like Alertpay) then change it back to Paypal on your real paypal account. The exchange would look like this:
Your (scammed money) paypal -> 3rd Company
3rd Company -> another virtual wallet
Your other virtual wallet -> 3rd Company
3rd Company -> Legit paypal
To be extra careful you can use two different Companys to transfer your funds.
