Move left sidebar to right

This is not possible because of the theme's design. Sorry.

I've got it with the following CSS. So I have two sidebars on the right: hobbyblob.com

The only problem is that if left sidebar doesn't have any blocks in it, it still takes space, which is ugly. I hope to sort it out, may be with somebody's help?

body.l-m-r-eq .outer,
body.l-m-eq .outer,
body.l-m-eq .outer {
  margin-left: 0px;
}

.colmain {
  float: left;
  width: 75%;
}

.colleft {
  float: right;
}

body.l-m-r-var1 .colleft,
body.m-r-var1 .colleft,
body.l-m-var1 .colleft, 
body.l-m-r-fix1 .colleft, 
body.m-r-fix1 .colleft, 
body.l-m-fix1 .colleft {
  width: 25%;
  margin-left: 0px;
}

body.l-m-r-eq .colleft,
body.m-r-eq .colleft,
body.l-m-eq .colleft {
  margin-left: 0px;
  width: 25%;
}

#sidebar-left {
 margin: 20px 10px 10px 10px;
}

body.l-m-r-var1 .outer {
  margin-left: 0px;
}

body.m-r-var1 .colright {
  width: 240px;
  margin-right: -330px;
}

Got it!
