Give us a little time as we are already working on yootheme subtemplate as well as an upgraded bs5 template. Did you know that the myaccount section of j2commerce.com is the same myaccount page you are wanting to change? 

Do you how to call the peoduct object in that page? It's not The same as the order item object that is normally called in there, 

I will work on some documentation later to show how to customize the my accounts page and get the product object so you can pull whatever data you need into that page.
