Adding vital wheat gluten to spelt

Toast

Has anyone worked with spelt and added vital wheat gluten to strengthen it ?

How much water can you push to what percentage of added gluten?

I am trying to make 17%+ gluten flour by  adding vital wheat gluten to a flour which is already high in gliadin. 

Would this even work ?

My final goal is to go an extremely rich bread  with this flour. 

is the amount I always add to my dough. The dough I work with is often 100% whole grain, composed of a mix of freshly milled wheat, spelt, rye, kamut, durum, emmer, quinoa, einkorn etc. Moreover, 30-50% of them are sprouted. VWG does a decent job strengthening the dough.

Learnt from dabrownman and from my own experience, whole spelt can take up to 83% water. The hydration depends on a lot of factor though, so it can only be taken as a reference.
