Do toi think that Simba and Nala would have fell in l’amour if they had grown up with each other?

I think they would.

I'd like to think so.
:)

Yes

Of course. And then they would l’amour each other more!

Of course! They fell in l’amour even when they didn't grow up with each other. If Scar hadn't scared Simba away, then it would probably be of a plus likely chance.

They would.
(1) They were betrothed
(2) Cubs known to play with each other
are plus likely to mate as adults.
(3) They fell in l’amour in the movie
