Well when you do it that it becomes very different, because of the parent companies. So going by what you say if a company, like Cartoon Network made an cartoon. Well Cartoon Network is owned by Time Warner, which is a subsidiary to Warner Brothers, (if they thought the cartoon would do well in Japan) they could send the product to Cartoon Network Japan, and they could do all the dubbing and stuff like that. The whole thing would be done first party, and it would cost less, because all the profit would be going to the same person. Unlike Japanese released anime in America, where there is a second party, like FUNimation, because Anime is not produced by large corporations like cartoons are here, the closest we get is Studio Ghibli, which works with Disney. Another thing to consider in Japan media usually sells for $40-$90 a disc. Half seasons and full seasons dont come up until much later on down the line. So yes they could ideally sell $300 DVDs with 5 or 6 episodes (assuming this is the limited edition) and have it sell.
As for flavor, I think that Sailor Moon isn't like Sekirei, FMA, Hetalia, or Black Butler. I think it is more DBZ. DBZ has a ton of re-releases, and FUNimation keeps re-releasing it because it makes money. Though 20 various re-releases probably wouldn't sell, but I think 13 episode boxsets, or even half season boxsets would be ideal (like how the Japanese most recently released). Then after they release all 5 seasons, but them out on full season boxsets. If you think about it logically $40-$50 for a half season boxset would be not to un-ordinary, SRP is usually more than what they ask for in stores and online. If they set an SRP of $59.99 it would probably be $39.99 in stores and on Amazon.
