Fascinating topic! Love it. Lots of great points here.
I find it interesting to consider a director's body of work to find the thread which may be (or may not be) woven through all of their films, their celluloid fingerprint if you will. What are they trying to explore in their films and what are the recurring motifs and themes that show up again and again? Why do they do what they do?
Peter Weir is an interesting director because his films run the spectrum of topics and don't necessarily have a singular note that resonates through all his films. Although, now that I think of it, many of his films are about the triumph of the human spirit, very epic, sweeping stories about (mostly) men who take on monumental obstacles or confront personal challenges or defy the odds stacked up against them. As for Weir's style, I'm not certain about that. Does "Dead Poet's Society" have the same fingerprint as "Mosquito Coast"? I wonder. I'd have to revisit them, or his film, to make a call on that.
I think style is sorta like a fingerprint, it is unique to that director. It's what makes a Wes Anderson film a Wes Anderson film and not a Jane Campion film. It's a voice. We know who is in the other room if we only hear their voice and don't see them at first. And we, as cineasts, grow to expect certain things from certain directors just as we would with our favorite musicians, bands, artists, etc. Mick Jagger never set out to make a style for himself, he simply WAS (and still is!) Mick Jagger and I don't think Scorsese set out to find the "Scorsese" style, either.
I came across this and thought it worth sharing

OK, tired now. Time for sleep. Good stuff!
