Mormons are Mormons.

The writings of their own founders indicate that Mormons did not consider themselves part of any Protestant church. They regarded Protestants in the same light as they regarded Catholicism, which is to say very negatively. Mormons wanted no part of either and regarded both Protestant and Catholic as being in serious error.

Interestingly one can see the progression (or rather regression) in the ages in which "the great apostasy" happened -- the first reformers believed the church went off track in the middle ages. Then the Baptist groups in the US believed this to be around Chalcedon or earlier

And Joseph Smith, took this idea and pushed it back even further in his teachings to apostolic times.
