I am wondering if it would be possible to swap out the MOSFETs on the picoUPS-100 by Mini-Box for higher-powered ICs. I know it would void the warranty, but it would be great to get a little more juice out of the device:

I actually have an inexpensive hot air rework gun, so I know HOW to modify the board. However, my electronics education stopped with basic passives, so spec'ing out MOSFETs is a little beyond me. What properties (beyond package type) would I need to consider when looking at possible replacement MOSFETS? Would I need to change any passives on the board to support the higher power?
Also, would there be anything wrong with connecting two of these boards in parallel?
Thank you!
