Groose's character trope was recycled from Linebeck was recycled from Midna. It's a very effortless way to give the illusion of character development. Groose just happened to have "cronies" as you call them because Skyward Sword had a generic school type setting on Skyloft so it seemed appropriate for the asshole to have some sidekicks.
You are going to have to make a better argument for why Groose is like Linebeck and Midna.
Midna and Linebeck are fairly bad comparisons for Groose if your main point revolves around there be a lack of, or "fake", character development. One major problem is that you have no evidence to support the "illusion of character development" you claim Groose falls victim to. This is significant because your examples (at least in the case of Midna) show huge character growth throughout their respective story lines. In fact instead of supporting your argument you decided to include characteristics of Groose (as in him being a highschool bully) which in fact plays into his character development later in his story arc when he decides to swallow his pride and help link; ultimately evolving into a heroic character.
If the character trope you are talking about is "the asshole" then sure he is similar to Linebeck and Midna. But "the asshole" is too broad a label to simply say that Groose is a recycle of Linebeck or Midna. Ganon is an Asshole, all the villians are assholes, Linebeck, Midna and Groose are not the same as each other and not the same as any of the Villians. Those two characters [Linebeck, Midna] were mean or unfair to Link, but had a different relationship to him than Groose did. As they needed Link's help to accomplish their goals they took advantage of him, as well as taunt him. [In Midna's case at least, I forget how often Linebeck deliberately tried to mock link]
Groose is more similar to Mido, it's almost exactly the same situation, Link has a childhood lady friend who the neighborhood bully wants to be his girlfriend. Groose and Mido don't want Link's help at all they badmouth him and stand in his way. The only difference is that Groose goes on to gain links trust and grow as a character.

The Man may be my favorite character in SS.
I don't feel there is any need for anyone to look much like Groose but I would like to see a character who has some of his characteristics again.
