Add 50 more PCIe lanes, double the bus width, 270mb of cache, 60 cores and a communication protocol then get back to me.
Anandtech ran the numbers a couple years ago and an EPYC processor spent around 60% of its budget on Infinity Fabric (up to 90% of used power with only a couple cores being used).
An M2 based chip might get more done, but it won't use much less power. In truth, I'd guess there's a good chance it bottlenecks on the IO and performance doesn't increase as expected (without widening IO further with all the extra power costs).
