It does seem to me that it would be useful to construe @facs so that it could refer to other kinds of facsimiles as well, since otherwise there's no provision for them. For instance, to link paragraphs of text or individual poems to the audio files of someone reading them aloud--this seems like a useful application of the idea of "facsimile". I confess I had in my head that that this was already the intended usage of @facs but looking at the Guidelines I see I'm wrong…

This may be a separate question, though, from that of whether @facs is right for your usage with <timeline> here.

best wishes, Julia
