SPIKE stickers?

I've actually had this idea for a while, but never thought seriously about actually doing something with that idea..

I was thinking... Would anyone be interested in buying stickers of my characters?
4 or 5 inch tall stickers of each character, probably even with three or more versions of some of the characters (like kid Sam, young teen Sam, older teen Sam). The characters would be drawn in a chibi-like style.. not like the ones I previously drew that had really creepy, hollow eyes... But more like the Cain paperchild I made, or the Spike paperchild with the christmas hat.
Hang on, I'll find them...



This type of chibi-style and with white edges around them (because personally I think the white edge would make it look pretty neat). Perhaps a wider edge though, but something like this.
The stickers would be of high quality. I've already found a company that prints stickers in any size and shape, in high quality vinyl, so I was thinking of getting some stickers made there, and sell them myself.

So, yeah... I'm not sure how soon this would happen, as I would have to fund it myself to get the stickers made in the first place. But before I start thinking more seriously about it, I need to know...

Does this sound interesting?
