Past Mario characters return in Mario, Luigi and MLP?

I've been looking at Mario and Luigi from past games such as Superstar Saga, Partners In Time Paper Mario and such

and I've been thinking, should I bring them into the current story and have them teach techniques to some of the Mane 6 and Spike? it could make some interesting situations for the story if I do

Better just stick with the characters of the game or if you insists make these characters from the other games appear as cameos.

Just to not lost track of the narrative.

You could add them for Chrysalis' Journey. I mean in Superstar Saga for that Captain Goomba, they added Starlow. Perhaps Popple for foolishly steals Chrysalis' crown
