Sure, if you're willing to go to a resort or park-hop for a TS meal, then why not for a CS meal? After all, you're travelling to eat and the end result will be the same - you'll be full and won't have to eat for a while. But, if you would plan to only eat in the parks then you'll probably get annoyed at the time you'll lose by going to a resort to eat.
But, if you think about it - you could go to GF, Poly, CR or WL from MK, and the YC/BC from Epcot WS or DHS, so you have a lot of really close options. I think it's a great idea if you take your trip leisurely. It's something we may do on our FD trip too.
