Welcome to HF ferret
The 2nd layer wont interfere with a underquilt or cause problems with condensation - but it will help in "fixating" a unruly pad and reduce the chance of being bitten trough the layers.
Just remember that a underquilt goes on the outside of the hammock, not between layers(it needs to loft in order to retain insulation).
