That's fine; I have no qualms about receiving clones, and the fact that it probably doesn't have high IVs adds to the charm for me. I probably won't be using it competitively anyway, I just ultimately felt like having a Shiny Shedinja in my collection so I've been looking for a Nincada so I have a Ninjask as well, haha.
That's great that you want to take it back to the same route; I have a few guys from an original playthrough of Sapphire back in 2003 so I know the feeling, and it'll be great to take back this Nincada to the route myself. I have a SHiny Jolly Monferno w/THunderpunch that I don't need, does that sounds good?
