I think I'm going to go with this and see what happens. It gives me a 17.5 SRM and put me at 4.2% ABV.
6 lbs Pale Malt, Maris Otter (3.0 SRM)
2 lbs Munich Dark (BestMälz) (12.7 SRM)
1 lbs Brown Malt (65.0 SRM)
8.0 oz Biscuit Malt (23.0 SRM)
8.0 oz Oats, Flaked (1.0 SRM)
8.0 oz Simpsons Double Roasted Crystal
6.0 oz Pale Chocolate Malt (200.0 SRM)
I was ready to go with this as my next beer. I cannot find the Simpson's double roasted crystal local.
More beer has viking dark ale malt, that might be my experimental exploration ingredient.
