Probably not with DIMM modules, as longer traces mean higher latency (speed of light is ~30 cm in 1ns). GDDR typically uses larger buses (more wires) for higher bandwidth, even more so for HBM, so DIMM would be hard. Maybe CAMM would be up to the task?
It certainly seems feasible from an engineering perspective (though it does make cooling harder), at least for mid-range, not H100-class HW, but it prevents market segmentation, so EOMs may not be too interested (as long as no competitor does it).
