The original American footage blends so nicely with the Japanese footage that at times, I thought that the American footage was in Shinkenger. The minor shinyness of the original suits has been since worked out and it barely makes a difference. Surely, they could redo Gokai Silver like they have the Japanese scenes and the cockpit. It's a highly minute detail that could be easily reshot.
Goseiger being adapted later or as a mini series would be neater still because they could get another team to write a great followup to the original series. They only use the fight scenes as it is and given if Saban washes their hands of Tzachor after Starboard , they could really improve on the show.
If a drect adapt, it's Alien Rangers redux, but if it is laxer, they could really have a reboot on their hands, with Gobusters being the depressing sequel.
As Nnnkingston put it, the placement of Goseiger after Gokai is not much of a big deal other than to people whom are OCD about series order because they'll go insane if it goes out of order. I highly doubt Saban sees it as a huge deal , given they have refilmed the Legendary War scenes and cut out Go-Jet. This brings up a huge question of how Tzachor will deal with those episodes or will they be rewritten, but hopefully, they get someone new for it.
