Can I make this affiliate model work?

Can any Spreadshirt expert help me?

We’re looking to set up a coalition of talented designers under our brand, a sort of micro marketplace, where with each sale - whatever partner store a product was purchased through - the designer, the referrer and ourselves (as the host brand) are all rewarded?

Not a straightforward affiliate scheme. The model is explained here: https://drive.google.com/file/d/11Sf7j4TLdHedhPxVJLh888rha_EAmVmV/view?usp=sharing

Can you see a way we could make this work with Spreadshop stores, or perhaps SPOD on Shopify and a third-party affiliate plug-in? Or should I look elsewhere?
