If the grilles work, a couple of birds will just clog the grille. If the grilles don't work, the birds will just get diced by the grille, leading to a unpleasantly coughing engine. Fighter jets that operate from un-improved air strips often have these grilles, but as a protection against rocks. The ...

And the Space Shuttle's SSME engines were built for the ascent to LEO. They're not vacuum-optimized.

It would be more worthwhile to build a ferry that can't withstand atmospherical reentry, and just commutes between earth and moon orbits. Maybe some gentle atmospherical braking, but not more.
