Jay Jay's Mysteries Lost Episodes & Characters

Hello, this is my first time posting here and I came across this forum from watching several Lost Media videos such as from LSuperSonicQ so I knew I had to make a thread while I was researching a specific topic. I am in the process of revamping the Jay Jay the Jet Plane wiki site since it seems to have been left in quite a mess, and while I was going through the pages, I came across a couple characters who stood out to me because I remembered seeing toys of them when I was a kid, though never seeing them in any episodes. Season 4 of the "CGI/Main Series" that most people are familiar with was under the name "Jay Jay's Mysteries" where it featured Jay Jay and a new Spanish plane named Lina where they solve mysteries and learn about the environment and stuff along the way. Sometime in the early 2000s, there was a poll on the PBS Kids version of the website where fans were asked to vote on which character they would like to see. Montana, a cowboy-hat wearing safari plane won the poll (and subsequently appeared) but the site goes on to then mention that everyone will eventually be appearing. Solar, Captain Bob and Truckee were the other three characters, and all four got toys in the "Wooden Adventure System". Only ten episodes aired in 2005 for Jay Jay's Mysteries, and Montana appeared in one or two. One single news article states that ten more episodes were scheduled for 2006, presumably where the three other new characters would appear, but there is no other information at all. Several people remember the poll and/or the toys but no one had a clue who they were back then, or even now, considering they never appeared. I researched this topic in 2022, and again in 2024, where I then decided to make this post here. I'm hoping to find literally anything new whether it's episode plots, 3D character model images, concept art of them or their toys, or anything that implies the characters made it into production other than a few sources (such as the wiki where anyone can edit) saying it was just outright canceled. I'm more well-versed with Thomas the Tank Engine content, though I watched Jay Jay frequently as a kid so solving a 20+ year old mystery would be really cool. I messaged the creator of the series on LinkedIn but have not recieved a response yet, though I am hoping that can be my first lead. I would be thrilled to know if anyone else has any ideas or leads!
