I haven't tried it personally, but my understanding is that this is 
incorrect.

The SMART template-switching primer is a hybrid oligo - the majority is 
DNA, but the last three bases are RNA.  So far as I know, the 
template-switching only works with a hybrid oligo, not with a pure RNA 
or a pure DNA oligo.
