Okay, I'll throw up an Old school Death Metal band for you gentlemen.
Vocals- Luc Lemay (Gorguts, Negativa)
Backing Vocals- Chris Reifert (Autopsy,Abcess, Machetazo(Guest))
Lead Guitar- Chuck Schuldiner (Death,Slaughter,Control Denied) RIP
Rhythm Guitar - Denis D'Amour (Voivod)
Bass Guitar - Scott Clendenin (Death, Control Denied, Talonzfury)
Drums- Flo Mounier (Cryptopsy)
Had different picks originally for Rhythm Guitar and Bass, those being Richard Brunelle and Alex Webster respectively, but I decided Scott and Denis would mesh better with the rest of the band. Not to mention offer a more varied sound and creative approach.( Not that extra creativity would even be necessary in a band with Chuck Shuldiner and Luc Lemay)

Traditional/Epic Doom Metal Band
Vocals - Messiah Marcolin (Candlemass, Mercy, Memento Mori, Colossus, Requiem)
Guitar - Tony Iommi (Black Sabbath, dozens of other bands)
Bass - Mark Adams (Saint Vitus)
Drums - You (Coffins(Japan))
I would pay any amount of money asked if I could to have seen this band happen. Messiah Marcolin is the greatest vocalist in metal history, period. You don't believe me, go pick up Nightfall or Tales of Creation by Candlemass, and thank me later. Tony Iommi is a must, not only is he seasoned guitarist, but many credit him with the creation of the traditional Doom Metal sound. Marks Adams is in on Bass, partly because I love St. Vitus, but more importantly because of his similarity in sound to Sabbath's Geezer Butler. The difference being that he is about ten times the bassist Geezer Butler is.You may seem out of place, not only is he Japaneses, but he is a founding member of Coffins. Which, for those not familiar with their music, are a more death metal oriented Doom Metal act. I feel that his plodding, desolate, and thunderously heavy drum sound would not only fit the big sound of the rest of the band, I'm of the opinion that he's one of the better drummers in Doom Metal today.
I could do a few more, but that required enough thought as is, might throw up some others later.
