This might be a stupid one, but can a zeitronix wideband replace your existing o2 sensor, so you dont need to weld in a bung.

A) The DME needs the nb02 or it runs rich till a certain throttle postion
B) The heat would kill the WB02 much faster

There are threads with info in this already, but the general consensus is no. The reason is you won't get accurate readings with the wideband being so close to the turbo, and also the bung will wear out much quicker than it is supposed to, since it's not meant to be put so close.

There is really no reason to put the wideband any closer than where it is supposed to go. The readings are as accurate as you're gonna get. Plus, the bung in the crossover is wired to the DME, whereas a wideband is there for the user to monitor/data log.

I got a bung welded in for $20 at a local muffler shop and they gave me the bung!

Keep the NBO2 in the factory position and add a bung downstream of the turbo. You don't want the wideband in the crossover anyways with all the exhaust pressure.
