Is it, or could it be possible, to store (image) assets with collections?

I ask as I'd like to transfer 100+ posts, each with associated images (some none, some one, some a gallery) from WP to statamic, but I want each project to be a modular unit, rather than a collection tree with associated assets tree that will just become a sprawling archive with no file-centric way to associate images with posts.

As such, I'd probably need to store posts as folders.

So, from:

root
    assets
        img
            project-01-01.jpg
            project-01-02.jpg
            project-02-01.jpg
            project-02-02.jpg
    site
        collections
            projects
                2018-01-01.project-01.md
                2018-01-02.project-02.md

to:

root
    site
        collections
            projects
                2018-01-01.project-01
                    index.md
                    image-01.jpg
                    image-02.jpg
                2018-01-02.project-02
                    index.md
                    image-01.jpg
                    image-02.jpg

I don't know Statamic well enough to know how this would (adversely) affect the admin panel experience or associated settings file writes.

Or maybe there's some way to build a theme or addon to support this? Again, I don't know Statamic well enough.
