Recipe Formulation - Starvation Point Porter

I'm trying to decide whether to "smoke" the porter or not but I'm looking for a dark brown rather than black beer with a hint of coffee/choc sweetness which is why I've chosen the Carafa1 and Pale Choc combination. I've come up with this:

Starvation Point is a place opposite the harbour gates in Whitstable, Kent, so called because it was where sailors and dockers used to look for work in the 1800's. Clearly some were luckier than others. I'm not entirely sure whether I'll use the Rauchmalz or not but I've got a couple of days to think about it.
