The issue here is that you are mixing in a solid instead of a liquid. There are two reasons why this doesn't make a difference. The first is that one of the examples cited of things mixed in is spices, which are not a liquid and are not being substituted as a binding agent of the dough, and even so they have the same status as fruit juices (Shulchan Aruch, Orach Chaim 168:7). Secondly, this case seems analogous to the halacha of bread made from flour of the 5 grains mixed with flour of legumes or beans, discussed in Shulchan Aruch, Orach Chaim 208:9. In that halacha, the Mechaber states that as long as it still has the taste of the grain it still gets Hamotzi.
This is not the same as fruit fillings (discussed in 168:7) for several reasons, but the simplest reason is that fruit fillings alter the way in which the bread is eaten, making it into a snack-ish food (see Magen Avraham 168:35), whereas your example of non-taste-altering additions would not.
Additionally, the Nesivos in his introduction to his Maaseh Nisim Hagada, in the section about hamotzi, says that all of the reasons for pas haba b'kisanin are just examples of things that would turn the bread into something eaten as a snack, and any bread item would depend on that factor alone. If your bread feels, looks, and tastes like bread, then it would be in the Nesivos' category of non-pas haba b'kisanin.
