Several of my businesses have been in this space. I specialize in helping businesses add product and service revenues on top of their existing channels. We could do an ideation session that would help you think of options to explore and if that went well there are other options. I absolutely agree with your assessment that services should add products and products should add services because in essence each is a packaging of the IP in different ways. It's going to come down to understanding your customers and what they need/want and also in segmenting the targets appropriately in your marketing/sales funnel.
