Do you have experience coaching software development teams? If so, I imagine transitioning into coaching for games people would be relatively smooth. If you don't have software experience, you might not be taken seriously, though. (Full disclosure, I am only a hobbyist game dev but I am a professional software developer and have received some coaching in the past.)
You should also be aware that you're unlikely to find people who lead large commercial game dev teams on this forum. I'm assuming you're also doing market research elsewhere.
