That looks like a good idea. In general waterway mapping in India is already pretty extensive but the big ones are generally poor in terms of riverbank mapping. This especially applies to the NW1 and NW2 here.
One big problem in India is that water levels and therefore the extent of the rivers varies enormously between dry season and monsoon season. Mappers need to be aware of this - otherwise you get results like here:
