So currently I have an Integration mode installation of Reporting Services on my SharePoint backend SQL server, however this cannot be configured because the SharePoint backend SQL server must be configured as a SharePoint WFE, but I am unsure of how to do this. Can anyone help

If you are installing in the integrated mode you need to install it on one of the Sharepoint Servers. (either existing one or you need to provision a new one, if it is prod probably second option will be applicable) Check this article for steps: https://technet.microsoft.com/en-us/library/cc261752.aspx
If you are configuring a report server to run in SharePoint integrated mode in a SharePoint farm, the report server needs the SharePoint object model installed. The object model can be installed on the report server by installing front-end Web server components of a SharePoint product on the report server computer.
