I just don't think that you're going to get much carryover in flavor if you mash a cereal like this. The ingredients are pretty basic:
Sugar, wheat, dextrose, honey, contains 2% or less of vegetable oil (hydrogenated or partially hydrogenated soybean), salt, caramel color, soy lecithin, BHT for freshness
Outside of the puffed wheat, I don't see much here that would seem like it would continue to have much of a flavor impact on the finished beer after going through the boil and fermentation. The BHT might help shelf stability a bit, I guess...
