No, I don't think so. You could do the 10:00 Lion King, followed by the 10:30 Safari FP, but I think you would cut into your hour-long FP window to do so. We saw the Lion King a couple of weeks ago (a highlight of AK, by the way!) and I think the show lasted close to 30 minutes. Add to that the walking time to Safari (not huge but not insignificant, especially given that you'll have to navigate around the crowd leaving the show), and Safari is pretty long, and you won't be able to make it to Tusker House by 10:45.
We found it challenging to fit in everything we wanted to do at AK because the shows we wanted to see are at the top of the hour, and they are pretty long. If you could move Tusker House back some, that would enable you to do Lion King and Safari first, or maybe you could move Safari up to before Lion King?
Good luck!
