I'm pretty sure this will work with no hack needed.

Try changing the vBulletin Options >> Allow Users To Change Styles to no, then in Styles >> Modify >> Properties >> User Selectable set to yes.

You should then be able to swicth to the style via adding the styleID# to your URL, but users should not see the selection box in their CP options, until you set the vBulletin Options >> Allow Users To Change Styles to yes.

To get the style ID number make sure you have your status bar visible and in your Admin CP go to Styles >> Modify and hover over the links for the style you want. Look in the status bar as you hover over the link and you should see the URL, at the end you should see styleid=##.

To add that to your forum URL just do it like this.

http://yoursite.com/forum/index.php?s=&styleid=##

where ## is the number of the styleID you are working on.

I'm not positive this works, but it should.
