Make a small batch and test it... Just because none of us have heard of it, doesn't meant that it won't work... just that either no one has thought of it, but you and the OP... or that no one has posted anything. WHAT IF... you do a 1 or 2.5 gallon batch and it turns out it works and makes great beer, then you're heralded a genius. Seriously, that's how people innovate, they try things, even when arm-chair quarterbacks are so convinced it can't be done. Hell half of my threads are experiments that turn out, or that buck conventional "wisdom," just to prove that we shouldn't repeat the same things we've heard all the time.
6 years ago there was very little out here on home malting or gluten free brewing, and now there's forums on GF on here.... and people have learned things, shared things.... give it a try.
