I doubt it. I've never heard of any encapsulation that wraps a layer two 
protocol in another layer 2 protocol. Depending on whose OSI model you 
subscribe to, of course.

People (programmers, etc) use UDP because it's connectionless and light, 
fast, and not overburdened with layers of check-and-retry logic. If the 
packet didn't get through, the higher layers are free to retransmit, which 
is in general exactly what they do.

In other words, don't bring a knife to a gunfight.
