I ran your ingredients through Brewer's Friends, and came up with the following vital statistics: OG 1058, FG 1015, ABV 5.7, IBU 25, SRM 27.
It is a little heavy for an English style brown ale (but right in the OG range for an American brown ale), and a little dark (if you care about color). You could drop a pound of the MO, and all of the chocolate wheat (or bump up the chocolate wheat to 6 oz. and drop the chocolate malt) - that would drop the OG to 1052, and the SRM to 21. I am not crazy about US Fuggles (Willamette makes a better choice, I think), but if you can get UK Fuggles, then you are in good shape.
