No, I do not see the need for such a page. In Sentai the concept of a redecoed Ranger is a lot more unique because such Rangers usually only make one-off appearances. Looking at the latest revision of the page before it was marked for deletion, there's nothing unique about most of the so-called "redecoed" Riders listed. Sharing of base body types is a lot more commonplace in Rider because of powers stemming from a shared source. It would be weird to say that Punch Hopper is a redeco of Kick Hopper, or for instance saying Rider 2 is a redeco of Rider 1. I'd guess that kitbashed suits like the future Riders from Zi-O would still count, but their suit modifications are a lot heavier for them to be classified as just "redecoes".
