Here's a take on the nicostick utilising a 3xAAA switched battery box.
I already have batteries and chargers for my cigars so it made sense to use AAA instead of AA. It uses a 901 or a 401 atomiser.

Bare box showing atomiser connectors

With battery and 401 atomiser attached

With 901 attached

Box closed with 901 attached and 401 next to it.
This mod allows you to use your favourite atomisers and different flavours in one box and NO you can't puff on both at once
