1. Impact would be a great place for young wrestlers to gain experience

Yes, New Japan was indeed burned by sending talent to Impact once, but it was nearly a decade ago and many things have changed. Impact has relationships with companies all over the US and Canada. They have shows from New York, to Florida, to Toronto, Chicago, and beyond. They do their own TV show, run pay-per-view events, and have a ton of joint shows with other, smaller companies all around both countries. The amount of exposure to different crowds, wrestlers, and environments that young wrestlers who have never wrestled, let alone even left, Japan, would be invaluable.
TNA was a singular company with a few tenuous ties with other promotions back when guys like Naito, Sanada, Okada, even Tanahashi in the mid-2000s, showed up and had a go in the then-Nashville-based promotion. These days, they have partnerships with so many companies that, as long as they don't make mistakes like "Okato" and just let the young wrestlers gain experience and travel North America, both on their TV, PPVs, and special events that air on Twitch and otherwise, it would be an amazing experience.
Think about guys like Ren Narita mixing it up with all of the X Division stars and so many independent wrestlers as well. Bigger guys like Yota Tsuji could have battles with men like Moose, Eddie Edwards -- Rhino! Plus, the local guys from the LA Dojo would be able to gain experience much closer to home. It's a win-win, as long as Impact treats them like legitimate wrestlers, not toys. There is more potential than possibly imaginable.
