characters who should have been in the meeting films

[minor muppetz]

I was reading about the Muppet Meeting Films at Muppet Wiki recently, and I learned that with the main exception of the first meeting film, the Muppet Meeting Films rarely featured appearances by recognisable muppets from The Muppet Show (though the monsters popped up from time to time).

However, are there any characters who you think would have been perfect to have been included in the films?

I think that the following characters would have fit right in:

JP Gross
Bill, Gil, and Jill
King Goshposh (he could have been called The Company King)
Dr. Bunsen Honeydew
Beaker
The Newsman
Fleet Scribbler (perhaps)
Mildred
