Yes, I can imagine all kinds of possible systems. The problem is that the right answer for "how do we use this" is very different between 8GB of HBM + 64GB of DRAM vs 256GB of DRAM + 128GB of CXL.
The relative latency, the relative bandwidth, the relative capacities all drive towards different solutions. That's why it's so unhelpful when the CXL advocates bring up HBM as an example.
