I think that as far as the {'Iv} is concerned, it is ok for it to bear type 5 suffixes.

As far as the {nuq} is concerned, although I don't think there would be any ambiguity if someone for instance wrote {nuqmo'}, neverthless I wouldn't go on adding type 5 suffixes, for no other reason than that it just looks too weird.

Although, admittedly, the temptation of writing {nuqmo'}, {nuqvaD} and/or {nuqvo'}, is just too great.
