Auto-Blog

I read in the description of this plugin that we could request new features here in the forums. Well, i would like to request a feature

Can we add the ability to have certain keywords setup on a per blog basis? Then, when feading in the content via RSS certain variable names would be replaced by those keywords? So if I have a user who wants to rank for "Atlanta Cupcakes" I could write an article like "if you are interested in X, please give us a call" and as it fead into their blog via autoblogger it would replace X with Atlanta Cupcakes. Does that make sense? Is this something that is doable?
