You could try something similar to what Bio::SeqIO::fasta does, which is set
preferred_id_type() to display the identifier based on various information,
such as the display ID, accession, etc. You could add a similar method to
Bio::AlignIO(), then have every write_aln() use that method for determining
what the displayed name in the alignment should be.
Beyond that, I'm not sure how you would go about making it easier beyond
iterating through the LocatableSeq objects (as you had already tried).
