You could borrow from pitch class set theory and call them: "Ordered
collections of the cardinal number seven", but I suspect that's not quite
what you're looking for:-) What's wrong with (as you mentioned above)
"13th
chord"?
And, of course, another issue is voicing since if you stack the tones in
2nds rather than 3rds, you'll have a tone cluster.
