This is something we can look at. As pointed out, mods can migrate to any site in the network at their discretion. What we like to do is watch instances of that, and look at how many posts were rejected by the target site (e.g. closed as anything but a duplicate). 

If it looks like questions going there _and_ being accepted is a recurring scenario, then we can definitely look at establishing a migration path. Right now, there's just not enough data to indicate if it would be a good idea or not. Not saying that it isn't, but we like to be certain before establishing the conduit.
