You should be able to use some Velocity like this:
#set ($display=1)
##change this to change which is today's display choice.
#iset ($version=$request.getParameter("version"))
#if ($UtilMethods.isSet($version))
#set ($display=$version)
#end
#if ($display==1)
ONE
#end
#if ($display==2)
TWO
#end
This code would display ONE if you went to it like this:
And TWO if you used
plus,you just change that first number by hand whenever you want to swap.
Although, if you just make each display piece a unique piece of content, it is trivial to add and remove them, no code.
I'd make a second developer page that just has all 5 on it for viewing.
