I think this bug report is getting a bit off-track beyond the original issue of just gamma/nu ambiguity. Please could we move the general discussion of when/how to alias glyphs over to bug #647443 ("Style: when and to what extent to re-use glyphs between scripts") and which I've opened for this purpose and populated with a full list of current aliasing that is in use, push some Python so that people can investigate further.
