What would be the name of a genre of Heavy Metal that plays all types of Metal?

I want to be in a Heavy Metal band (B player but I might learn other instruments and play that instead.) And I really like Thrash Metal and other types of Metal my favorite is Thrash. But I don't want to be like strictly Thrash. Like maybe on song would be Thrash and the next violent like Death Metal (Just without the growling.) Then I could make a Power Metal song or something. Also the vocals would probably be a Tenor. Cause I really love the way Tenors sound in Metal (Like Rob Halford, Bruce inson, The singer from Helloween sorry I don't know his name I just recently came across this band.) Singers like that. Is there a Genre of Heavy Metal like this or did I just make one up?
