You could probably sub the light DME for wheat DME, since the wheat extract already has somewhere around 35% pale in it. Also, when are you going to add the honey? Different times in the boil will lead to different flavors, flameout leaves more of the flowery notes, boil leaves less, etc. Just some things to think about. Unfortunately (or fortunately) most of the time making your own recipes means just going for it and seeing what you like and don't like and adjusting next time. I might suggest doing half batches until you like it, just in case. I do most of my weird ones in small batches, lets you brew more often to make changes. Looks good though.
