Not to mention a centralized search system would be even more problematic in the fact that why do you even have market ward zones in the first place. Why not have a "teleport market wards" function on your menu...

Oh great... it's the same problem all over complicated imitation of an AH with 20x the complexity.
Again, there's no need. You can implement a direct consignment system. The name of the system isn't important. What matters is that is functional.
Market wards are functional, and every single feature of an AH can be implemented into it. Keyword search, price history, centralized search, direct delivery.

It's not necessary more complicated than an AH, because besides the graphical interface, it's still a database, and works pretty much in the same way.

The advantage of doing that instead of completely scrapping the system and making a new one are twofold: Improving an existing system is less demanding, resources-wise, than making a completely new one. And you still keep the unique features of market wards for those that enjoy them.
