Are there hybrids that emerge as a new species?
Yes, this is called hybrid speciation.


  Hybrid speciation is a form of speciation wherein hybridization between two different species leads to a new species, reproductively isolated from the parent species


There has been a fair amount of work on hybrid speciation (see here). Hybrid speciation is often thought to be more frequent in plants than animals. In ferns for example, we estimate that 7% of species emerged through hybrid speciation (Otto and Whitton 2000). Typical cases of hybrid speciation include changes in ploidy levels (examples include sunflowers). Hybrid speciation also occurs in animals such as the lonicera fly to cite just an example.
