Changes

Your font has no Small Caps variant? Do you need Small Caps switching depending on the \it, \bf, \bi, \tt, \ss, ... ? Here is the recipe for generating and installing Pseudo Small Caps (small letters are scaled down versions of capitals - typographicaly not clear solution but if the font has no real Small Caps...). The example is done on Latin Modern family but can be applied to another Type1 or font. (Note: pdftex doesn't handle this sort of transformation on TTF font typefonts.)
