I don't think it would work. Super Sentai is just too obscure in America. People are aware that PR uses Japanese footage, but that's basically the extent most average viewers know about Sentai.
Marvel doesn't really have any stakes in any shows beyond Spider-Man. While Marvel may have helped produce Battle Fever and Denjiman, they had no hand in Sun Vulcan (It was associated to Marvel by proxy since it was intended to be a sequel to Denjiman), and I think thanks to Toei's contract with Saban, they have more control over those 3 series.

Disney doesn't care about Sentai and Power Rangers, while Marvel doesn't really have any control over the series they helped produce anymore, while Saban has no reason to share with Disney nor act as an in between for Marvel and Toei (Profit share with an unaffiliated company for no real benefit? Saban is a bit too money hungry for that).
