Since liquid nitrogen and liquid oxygen have different densities and

nitrogen may be removed and oxygen passed through the engine while the
nitrogen is passed around the engine and heated to a lower
temperature.

     Oxygen:   -297F  71.2 lbs/ft3
    Nitrogen:   -321F  50.5 lbs/ft3

As you know, at the -297F of LOx the element of N2 is still a gas, and
as such easily excluded, on the fly(sort of speak).  In which case
you'll have yourself a full blown H2/O2 scramjet that'll fly
suborbital for as long or as far as your onboard cache of LH2 holds
out.
