No, it wouldn't hurt to have a tomboy princess, nor will it hurt to have a disabled princess. Those ideas will get little to none backlash. Adding LGBTQ princesses though, will have TONS of backlash for too many reasons for me to even say. I'm not saying it's a bad idea though, but people who don't support LGBTQ they may consider Disney as inappropriate which can result as people suing Disney, and Disney could ultimately lose a lot of money. But on the other hand, there are a lot of LGBTQ supporters out there. Either way, there will be some negativity and some positivity. Just like before, when Disney added racial statements inside their movies, some people supported them and some did not. I hope this makes sense lol
