I have owned a MW TP for 9 years. I love the one box solution and the MW sound. So, this mod holds great appeal for me as an upgrade. For me, and I suspect many others, for this box to be competitive, it would need to be Roon Ready and play higher rez DSD (128, 256, and 512) as well as MQA. As you point out, Oppo should be able to accommodate those concerns with simple firmware updates.
Very exciting.
