Yes increasing the drum diameter is the idea, gives more cable takeup. The epoxy blob gives it a little push right at the end of lever travel.
Campagnolo made a lever (shown below) that had a large(r) drum on the RH lever for more cable take up - presumeably for wide range setups.
This is a rare part.
