Wile dextrin and NC Lacquer are both binders in pyro, they are very different. NC is soluble in organic solvents and not in water, dextrin is used from water (perhaps with some alcohol added).
Certainly they are not a weight ratio replacement for each other. You would have to rework the compounding to get them to work.

In certain compositions the Dextrin is vital! I tried to make a batch of Lancaster Chlorate Silver stars for NYE and they got messed up. I tried Red Gom first which for some reason didn't seem to bind them properly. Might have been the huge pile of bright aluminium. But after that I sprayed them with some NC-laquor but they still didn't seem as hard as I've made them when I used dextrin before.
The dextrin also slows down some compositions (Like Lancaster Chlorate Silver, it uses 18% Dextrin).
