It would be too hot and too expensive. You can skip the copper media and go for an SFP/SFP+ pluggable directly - a full blown computer in the SFP module is yesteryear news. But at this point if you are assembling a cluster of sticks in SFP switch... you can just take some 5 y.o. USDT/Tiny and have a full blown x64 computer with all the power and virtualization you need.
