Heteropaternal Chimeras?

I've been dipping into the topic of people with 2 sets of DNA, who are technically known as chimeras.

Basically, a couple of fraternal twins merge in the womb, into a single person.

Sometimes fraternal twins have 2 different fathers, by a process known as heteropaternal superfecundation.

So, given that fraternal twins can merge, and also given that fraternal twins can have 2 fathers, the possibility is raised that one person could have 2 fathers. 

Maybe in practice it wouldn't be feasible.  But inquiring minds want to know!

Has anyone ever had
More than one dad?
