Nothing wrong with any suggestions. You should submit them in the product feedback section if you want your ideas read by those who could choose to make the additions to the modeling choices.
My personal choices would not be anything more than one basic nylon string classical, but even that is not something I need for any of my performances.
I suggested publicly and submitted my thoughts about adding back the original 1.71 acoustic guitar models in Custom Bank 1 in addition to the 1.81 acoustic models that have not met with any resounding delight because of their inherent ambient sound in the patch that cannot be adjusted. I simply thought that while tech is working on the acoustic alternate tuning bugs, they could "easily" put the 1.71 acoustic models into Custom Bank 1 for users to have the choice of either or perhaps some of each?
Also - perhaps you were not aware, but Line 6 produced a Variax Model 700 Acoustic which did have at least one nylon string model in the models on that guitar which were mainly similar to the electric guitars acoustic patches, but did have other different acoustic guitar models. Someone who has or had one of these discontinued guitars might be able to elaborate more than I. Perhaps you could get one of those guitars?
All the best,
