The problem is I have zero modding experience.
And you're never going to get any if you only rely on others to materialize your ideas.
I realize that it doesn't stick to the theme of Oblivion too well buy hey, who cares?
The people who you're asking to do your work for you.
Comments on improving the idea of the mod are also welcome.
Frankly I think you're better off just coming up with a poison you could put on your arrows which has the same effect. You're just over-complicating things by wanting the syringe. That would require alot of work on someone's part just to come up with animations, and I doubt very much if you'll find anyone who's going to be interested.
