I agree with most of those cuts. I think Smash 6 should cut most of the third-party characters, some of the Fire Emblem characters, some Pokemon plus characters that are obscure or jokes like Duck Hunt, ROB, Wii Fit Trainer, and Pirahna Plant.
Basically, I want the next Smash to have about 90 or more characters by cutting about 15-20 characters (at least), but adding about that much as well. There are some fighters that you could probably turn into echoes as well, like perhaps combining the younger Links.
