Hmmmm I've done all those things with WB skins in the past..... Animation, buttons on the side, Hover text, my BlackBoXX Ultra skin even has the titlebar on the bottom of the window!! But you know what? people don't really want them!! They might say "oh, that is different" but ultimately not many download them..... I don't mind that, I make 'em cos I like them, and because I like my stuff to be different, but I guess if you use download numbers as a guide then people do want familiarity with just a little bit of pizazz. It's a fine line......... 
Also, years ago, I was constantly berated for what people called "huge" titlebars, but these days people can upload a skin with a massive titlebar, and downloaders don't even mention it, rather, they call the author a genius!!
So, I reckon that, unless you walk that fine line that I mentioned, you won't please most people. Personally, I will just carry on doing what I've always done. Sometimes people like them, sometimes they don't........
