Personally, I found their interactions in fanfics interesting. Now, I don't know myself why I ship them, but there could be several reasons:

1) Aegon / Arya situation would be similar to / a replay of Rhaegar / Lyanna story. And GRRM is quite big on whole "history repeats" thing.

2) Aegon and Arya are both rather mysterious characters, Arya being a faceless man, and Aegon being virtually an unknown (starting from the question of his identity).

3) As I said, their personalities make for interesting interactions.

There is more, but I can't remember right now.
