Connecting a DCFIFO and a SCFIFO back-to-back is very easy. This would allow you to double the size.

I'm not sure whether 'directly' instantiating the fifo in your code (use the MegaWizard generated code to see how to do this) would allow any size fifo, but the .pdf doc looks like this would work ok.
