If it were me, I would only add just the Carmel 80 or the Honey malt, you could even do a 1/2 lb of each, but I wouldn't exceed a pound. I'd also drop RB and do a 1/2lb of chocolate, and I'm not sure if you would really need the Dark DME, but I've never done PM's so I don't really know.
What's your target OG?
The maple syrup sounds interesting, but possibly easy to over do. Everything else looks pretty good.
