I think every team gets an international player slot. Using that slot on a kicker is the most practical and realistic use for it if you don't already have a 'franchise kicker' like Justin Tucker. If we were really shooting for a one in a million pie in the sky feel good story we would bring in some Rugby Star TE or champion Sumo Wrestling left tackle except when you looked at the fine print their level of stardom in their previous sport would be highly exaggerated, therein why they gave it up for a tryout. Kicker is absolutely the most likely position to find an international gem. Usually when some Rugby 'star' comes to the NFL looking to play RB/WR/TE they are basically the Kevin White or Tim Tebow of Rugby, and their chance of success would be similar to, if not less than, the chances of one of those guys succeeding at Rugby.
