What's the problem of dealing with non reverseable transaction if you going to use escrow?
Using an escrow does not waive the problem of you scamming others. Since you are going to send from WU, you can reverse the money after months of doing the exchange and having the bitcoins with you while claiming fraud or chargeback.

They cannot protect a buyer from a claim that is months later after the transaction.
