Both workflows mencioned are acceptable when modelling a liner. A good point to highlight is that when you are creating the liner in a different Mechanial model you need to apply the contacts between the liner and the composite part.  A suggested feauture to use is the Thickness from CAD Geometry in the modeling Ply dialog. This allows you to have a varying thickness through the liner.

A last comment, if you need to simulate effectively the filament winding process the third party tools are suggested. This way you will get an accurate representation of the liner in terms of thickness and fiber orientation.

Hope this helps you modeling!
