Nice, you're taking it from the Settings, I like your approach more.
But be aware of ISPN-883, just solved.

The way I did it is create a HibernateTransactionManagerLookup class that implements org.infinispan.transaction.lookup.TransactionManagerLookup and looks up the transaction manager with Settings.getTransactionManagerLookup().getTransactionManager(properties)

Definitely; in which project would you store the common
TransactionManagerLookup wrapper?
I would be fine in depending to the second level cache module, I'd
assume that anybody having setup Infinispan and Hibernate would use
the second level cache too, or at least have no issues having to
depend on it being classpath.

We could add a simplified EmbeddedCacheManager constructor to maintain
most of the complexity of building a cache via a configuration but
overriding components via provided instances, this relates to a brief
chat I had yesterday with Vladimir about a forum thread [1]. Maybe
easies way is to expose the GlobalComponentRegistry during the
configuration phase, as overrides for internal components?
