It really depends but there are exceptions in which you need to keep a copy of the original forms. Keeping remodelled forms of those types is to give you a more flexible platform to work with.

Here are some examples where you will need to keep their base forms and their potential reasons why:
 * Chitose and Chiyoda both starts off as Seaplane Tender [AV] but after a few remodelling they become Light Aircraft Carriers [CVL]. However in their AV form they are required for two world 5 expeditions, namely expedition 36 and 40.
 * Taigei starts off as Submarine Tender [AS] but once remodelled (blueprint also required upon the initial remodel) becomes Light Aircraft Carrier [CVL]. However in Taigei's original form as AS she is again required in a world 5 expedition as well as a quest in order to gain two uncraftable equipments.

I'll let you figure out on the contrary if it is required to keep remodels or not.
