mods for the server?

ive been looking through some mods and i was wondering if anyone wanted to see if we could get mods into the server for a small amount of time. it gets kinda boring digging and making houses. why not have some fun, theres a couple of sweet mods out there like: having gernades, sea turtles, having lvl ups like an RPG game. even tho we have that for jobs and such. the timber mod, a plane mod, pokemobs,trains to get from place to place, a team fortress 2 mod, more creatures and weird ones, turrets or guns, herobrine in the game. theres a website that tells it all. i was wondering if possible to have it for like a week or a special event. get people to come back and enjoy the fun.
