Note the Xenon processors are server grade cpu's over desktop cpu's The biggest advantage of them over i series is the larger L3 cache over i series.. Most server cpu motherboards have more pci lanes then your average desktop board so quad sli is a larger benefit on those cpu's then i series also the ability to address larger memory pools and The ability to use ECC ram. Sense dolphin only leverages 2-3 cores (with lle audio spawned on its own thread.) Your not going to get the same performance as you do not really have a way to leverage a Xenon series cpu off dolphin.
where the main advantages of xenon is when you need 12-24 cores.. not just 8.. If dolphin was able to leverage multi core even multi core in parallel the Pentium anniversary edition and i7 processors would just get destroyed in terms of performance buy it..
really the only advantage you might have if you are running dolphin though a esx server with cpu & gpu passthough where you have dolphin running in a VM (say connected to a steam box with different os's virtualized.

To split up the 2 (3 with LLE) into more threads would mean you would have to split the emulation of each core into multiple threads. Which then brings in issues of waiting for cores to sync up and a shit load more bugs. It would be way to much work for something that probably wouldn't even work.
