I wonder what happens if you like take the thing out of zbrush and use marius silaghis ( killed the last name ) subd recovery!!
It would be the same as Dynameshing in ZB with a lower resolution. Not a good way to create a lowpoly, especially if you have source boolean objects on hand. That said why not give it a shot, experiment a bit
You should triangulate it to be on the sage side. Because it does not change the shape of your mesh it wont effect danymesh but ngons can behave different in max than in zbrush.
I wrote a more comprehensive tutorial on this workflow in Technical Talk - <a title="Link: http://polycount.com/discussion/168610/proboolean-dynamesh-hardsurface-workflow-tutorial" href="http://polycount.com/discussion/168610/proboolean-dynamesh-hardsurface-workflow-tutorial" target="_blank" rel="nofollow"><span class="post-color-green">www.polycount.com/discussion/168610/proboolean-dynamesh-hardsurface-workflow-tutorial</span></a>
