Brown Ale Base Recipe for Pumpking Ale, Thoughts?

I am planning on using an American Brown Ale as the base starter recipe for my Pumpkin ale. Looking for opinions on some feedback on what others have done.

Should work fine.  Many recipes are sort of based on ambers.  Big question, to me, is whether you want a pumpkin-focused beer or some hop counter-punch to it. 

But even among commercials there are many different styles of pumpkin ales.

  I 've made 4 pumpkin ales this past fall, 2 with a brown ale base and 2 with a pale ale base. In the lighter versions I used 8 lbs of maris otter and 1 lbs of 40l crystal malt. Even though your using pumpkin (I've always used fresh) ,it,'s the spices that come through. Allspice,cinnamon,nutmeg, and a touch of clove, cloves can be overwhelming if used in excess.
  That said I preferred the lighter base better. Actually the color is a bright copper which looks alot like pumpkin. But there is more than one way to skin a cat, ain't there?
