Suppose Ultimate’s Classic boss system was used in Smash Wii U. What bosses would characters face?

Exactly as the title says. There are unused boss icons in Smash 4, implying that we would see how much health they have at one point: https://www.ssbwiki.com/Unused_content_(SSB4)

So this got me curious to question a what-if scenario where in Smash Wii U first, certain characters fought bosses thematically matching said characters instead of Master Hand. Here’s my potential list of which bosses fight what characters:

Viruses: Yoshi, Kirby, Ness, Dr. Mario, Wii Fit Trainer, PAC-MAN

Ridley: Samus, Fox, Falco, Marth, Roy, Zero Suit Samus, Duck Hunt

Metal Face: Link, Sheik, Sonic, R.O.B., Shulk

Yellow Devil: Pikachu, Olimar, Mega Man
