Sounds interesting, I did an Old Ale a while back that turned out decent, and had a sorta similar recipe. I went lighter on the hops for a more traditional old ale though:
9.00 lb Light Dry Extract 67.9 %
1.00 lb Caramel/Crystal Malt - 60L 7.5 %
0.50 lb Barley, Flaked 3.8 %
0.25 lb Chocolate Malt 1.9 %
2.00 lb Brown Sugar, Light 15.1 %
0.50 lb Molasses 3.8 %
1.00 oz Target [11.00%] (60 min) Hops 6.0 IBU
1.00 oz Cascade [5.50%] (20 min) Hops 1.8 IBU
1 Pkgs Belgian Golden Ale (White Labs #WLP570) [Starter 500 ml] Yeast-Ale
This went in the fermenter on 9/15/06, went to secondary (way early, oops) on 9/30, FINALLY finished dropping the gravity 10/15, bottled FEBRUARY 4TH!!! Obviously I wasn't hugely concerned with this beer, just too much other stuff going on. Still, it came out ok, and I still have some of it now. Hopefully yours will ferment out faster since you're pitching on a cake. I'd love to hear how it turns out
