No, unfortunately; the information available to the accidental-setting rule 
is only the set of accidentals in /previous/ notes and key signature. An 
unfortunate design choice, but one I can forgive because in traditional 
music simultaneous conflicting accidentals are rare.

No doubt, you know how to force accidentals. <f! fis!>

I don't see an enhancement request to solve this problem; the closest
is <http://code.google.com/p/lilypond/issues/detail?id=1134>.  The manual
does explain the limitation in the section on 
Pitches::DisplayingPitches::AutomaticAccidentals.
