Need a starting point for an S scale 4-4-0 or 4-6-0

Have you concidered some of the "toyish" Christmas train sets as a starting point?
I have one that sounds to be about the size your talking about.
Mine is a 2-6-0 but there are others out there that are different wheel arangements or one like I have could be kit-bashed into a 4-4-0 without to much trouble.
