An off-the-wall thought on your hover tests and nitrogen capacity: 
if your propellant tank has a manhole cover, maybe you can put some 
stainless steel floats inside the tank to fill up some of the ullage 
  volume?  They're available cheap from McMaster-Carr, plain 304 or 
316 stainless spheres with no mounting spuds.

This might let you do a partial propellant load without needing 
god's own GN2 supply.
