Here's my original post on soloing NW if you want the in depth details of my first win.
In short, the answer is, it's very possible for sch to solo NW, and reluctantly possible to solo NE as well. In fact, I would even go so far to say that sch can solo NW easier and more successfully than blm can. That is just from my personal experiences though.
For the 2nd poster, duoing with another blm, should make zones such as NW and NE quite easy. NW should be a breeze in fact. I recommend saving your gems on the final floor of NW for alacrity rather than parsimony imo (except for the boss). This will give you faster recasts on bind, which is your 2nd key to successfully and easily taking out the behemoths.
You will also be able to handle zones such as temenos east and North (or west?) rather well too. Although unlike apollyon, temenos areas are more luck based and you have less chances of getting as far or clearing as you do in apollyon zones.
Just have patience if you don't succeed at first. When I tried the first time a few years ago, I died on the first mob. Don't let it get ya down, just keep trying, learning, and adapting to overcome the situation. Good luck! ^.^
