I've never used Sibelius, but I imagine its sounds can be triggered via midi.
No. Sibelius is a score publisher, with SOME sequencer features. MIDI input is on a single channel, for the purpose of capturing notation from a keyboard or other MIDI controller.
You COULD prepare MIDI tracks in Logic, export a MID file and open it in Sibelius. Then Rewire Sibelius' audio output back to Logic. But I think this is far from what's required here.
