On the subject of Goradora, it isn't simply the colors that recall the larger toys, but the names of each component. Each one shares the same beginning syllable as the larger Predacon toy whom their colors evoke:
The Hun-Gurrr redeco is named "Dorara" (ドララ) and has orange as its main color. And Dragotron (ドラゴトロン) also has orange as his main color.
The Twinstrike redeco is named "Garara" (ガララ) and has green as its main color. And Gaidora (ガイドーラ) also has green as his main color.
The Blight redeco is named "Burara" (ブララ) and has red as its main color. And Budora (ブドーラ) also has red as his main color.
The Windrazor redeco is named "Barara" (バララ) and has blue for its main color. And Bakudora (バクドーラ) also has blue as his main color.
The Rippersnappr redeco is named "Jurara" (ジュララ) and has purple as its main color. And Judora (ジュドーラ) also has purple as his main color.
Granted, the shades
of color shared between each don't perfectly match up (especially with Dorara having a yellowish-orange while Dragotron has a darker orange, and with Garara having an olive green while Gaidora has a teal green), but there is still the connection via the shared syllables of ド, ガ, ブ, バ, and ジュ between each small/large toy pair's members.
It's less that Goradora's components "homage" the larger figures, and more of their decos being "themed around" or "inspired by" the larger toys.
EDIT: Forgot something. They aren't the same guys as the larger Predacons, either. They are the minions/footsoldiers of the bigger Preds. No, I don't mean that as in "The little green one serves the big green one, the little red one serves the big red one, etc." I just mean that the five smaller guys are commanded by the bigger Predacons.
