Didn't finish reading this thread, but would like to chime in with my experience.
Yes, you can blow through a filter, I did so for ~18mo at my last house. I would taking your pre-filter and cutting it into circles a few inches larger than the diameter of the duct. You can place between your fan and your filter.
IMO, the CFM loss from pulling to pushing is negligible as most people purchase fans with more CFM than needed to do the job.
