You will have noted that I said "Spliced" above, which wasn't mentioned in
the original brief. That's because you need more than one place notation at
the same position to get the alternative possibilities in the same
composition. A single method would be limited to 7 wraps - one of each type.

Of course what I haven't considered is variable hunt. This could allow you
to produce all 17 wraps with a single method, since there is no restriction
where they have to occur in the lead.
