I'd be cool to see cross-realm AH in WoTLK realms.

No. Realms are very different in that perspective.
Check the Trade page and you'll see that gold is way more expensive on Lordaeron and even crafted items because it's way harder to clear ICC for primordials/EOFs.
cross realm AH could only work if you got multiple servers with the same stats (xp, honour, gold, etc) and similar player bases.
on warmane this is not the case, and it would break economy if it were to be implemented because as was stated above, AH prices are very different between servers due to dificulty to get the items, level up profs, etc.
There is a reason for the separation, please don't add any more crossrealm stuff if you want lordaeron to survive
