Recipe feedback

First time making my own recipe from scratch. I was thinking of a gingerbread-y porter.

4 lb Light LME
3 lb Amber LME
1 lb biscuit malt
0.5 lb chocolate malt
0.5 lb caramel malt 80L

1 oz Northern Brewer hops for all of boil (60 min)
1 oz Northern Brewer (10 min)

1 tsp Irish Moss (10 min)
8 oz molasses (10 min)

spice blend (10 min)
1/2 Tbsp cinnamon
1/2 Tbsp ginger
1/2 tsp allspice
1/2 tsp cloves

White Labs WLP085-English Ale Blend

Thoughts? Suggestions of what to add/remove?

The biscuit will not do much unless it is mashed.

Personally I don't like spices in beer, so any comments I might have will probably not be very constructive.
