Thoth's sceptre may represent a head with wind pipe (trachea).
One piece of evidence pointing in that direction is that Thoth's other manifestation as a baboon (e.g. like Hapi, also a baboon) was associated with one of the four canopic jars holding the lungs.
By strange coincidence (if you look over the thread posted by Avry), we just covered something which may support your idea more directly however. The word i33t (M17-G1-G1-X1), when determined with M2, M3, M34, or S42 yields staff/sceptre/stick/rod etc. and when determined with V6 pertains to clothing and string! This is an interesting association as per your inquiry. I have to find a proper textual sample for you to see if the textile context makes sense with that word and a tool....for example there may be something useful in Junker's description of Seneb's mastaba....Seneb was a highly acclaimed OK-4 official in charge of weaving and royal clothing.
How could you weave these two origins together? Think of the head and windpipe of a ram and a tool used to wind and weave sheeps wool. The stiffness of a windpipe prevents it from collapsing during inhalation.
The association between the staff as a power and strength symbol similar to backbone and Djet pillar and textiles is of course the linen wrap of the mummy which gives it stiffness and allows it to stand. The wrapping of a mummy was a drawn-out process which took 35 days (documented in the NK) and this material was of course precious. And so here too, through mummification and linen use, you have an association going back to Hapi, baboon and Thoth. This semantic association is sort of like our dual use of "staff". It's a walking stick and also a work force. In either case it denotes strength and stability.
