As long as you'll insert obligatory references to Apollo and the moon landings, I'm happy.
To be more serious, the whole "hunters in the Pride Lands" has been quite done to death, and I haven't really seen any good versions of it. But if you have a new and unique take on it, then I can still be quite interested.
Basically, I don't find human hunters being the Big Black Monsters from the Black Lagoon for Lions as an interesting case. Yes, gun beats claws 100% of the time, we know that. But as you put it: why are the guns in the Pride Lands? This can make for an interesting story if you can create a good reasons for humans to target and kill Mufasa.
