I know, I know, so new and yet so eager to change the rules and/or make something new

Well, really there's lots of things I can see that might be added to the shadowrun world that would be really cool, or at least I think so. I have ideas for a SR setting 100 years in the future, with a few new (although admittedly not totally original) ideas, such as Mecha, plasma weaponry, alienware, a wireless matrix. I'm fairly confident of writing up enough over time by my lonesone, but while I can simply just keep my efforts to my group, I'm here wondering if I should turn this into a full scale project. As in, put together a decent sourcebook.
To be honest, I was always apprehensive about introducing new things into SR. I always ran into some kind of opposition and the general idea I got was that apart from a few questionable rules, canon and specifically the canon setting should not be tampered with. And I also got a whole lot of anti-anime vibes (I'd be flat out stupid to claim mechs as anti anime...well, maybe mechwarrior mechs, but I'm including both types in, so...)
In short, I was just wondering if this kind of effort or discussion is welcome here. If so, maybe I might be able to cook up something relatively decent with enough time

and I could toss my ideas against you guys. But if not (and it's pretty possible, seeing as how I can't find player settings (not counting adventures) anywhere, then I guess I'm too much of a dreamer =/
