Sure. Not many people do wifi, so it would be a pleasure to battle you :)
Just so you know, I was a Gym Leader, but then I got all 17 badges and moved up to E4. I then appointed a new Gym Leader. However, he only does Pokemon Showdown, so I battle the people who can only do Wifi (I can do both).
And also, protip: Post your messages to other people on their profiles, not yours.
Have fun on Smogon ^_^
