SAP Fiori based application for SRM 5.0

Hi Experts,

I wanted to know if there is a way to create Fiori like applications for SRM 5.0. The Fiori applications like Shopping Cart and all need SRM 7.0 but in our landscape we have only SRM 5.0 and we would like to evaluate if we can create custom UI5 applications to perform some operations like Approve PO, Approve Shopping Cart.

Any advice would be very helpful regarding this topic.
