Onigiri – Any store possibilities?

We are a small studio placed in Barcelona and we love the portfolio of this template.

The only problem is that we need a “store” on our website. Could we add some “commerce plugin” to Onigiri, to have a section SHOP on the menu?
Or, is there a way to unify the Onigiri with Hawea theme to take advantage of their store properties?

Any other ideas to integrate a small shop on Onigiri?

Many thanks in advance.
