For 5 gal I'd try the following to get the color without the excessive roast. This is real close to my all grain recipe I brew regularly.
8 oz BlackPrinz
8 oz Midnight Wheat
1 lb C-60/75
6lbs Extra light DME
1lb Dextrose
2oz Chinook @ 60 mins (~75 IBUs)
4oz of assorted finishing hops at flameout
4oz of assorted finishing hops in dry hops
Hops wise I think lots of late Chinook, Simcoe, Amarillo, Cascade, Mosaic, Galaxy etc work well for this style.
