rel="stylesheet" rel="alternate stylesheet"

[webarnes]

Not sure where to place css questions but here goes:

Are there any known problems with using multiple default external stylesheet?

ex.:
<link rel="stylesheet" type="text/css" href="bodyTmplt.css" title="bodyTemplate">
<link rel="stylesheet" type="text/css" href="innerBdysize1.css" title="innerBodySizes1">
<link rel="stylesheet" type="text/css" href="defaultColor.css" title="defaultColor">

<link rel="alternate stylesheet" type="text/css" href="colorTwo.css" title="colorTwo">
<link rel="alternate stylesheet" type="text/css" href="colorThree.css" title="colorThree">
<link rel="alternate stylesheet" type="text/css" href="colorFour.css" title="colorFour">

That's three defaults and Three alternates.

(id="size and positon")
I want to use a stylesheet for the size and position attributes of the constant Header, Top Nav and Footer.
It will cache once and get called to each page as needed.

(id="size and positon")
I want to create a different stylesheet for each page inner body size and position attributes.
the inner body of each page will vary .

(class="color")
I will create css to change entire color schemes with mouse click.
Cookie will keep theme constant from page to page.

Before I get elbow deep in rebuilding my stylesheets does there appear to be any problems with this idea?
