Excellent point: yes, there is a risk of gardenpathing. In a sense, if we can get away with "du'u ... Q-kau", then we should be able to get away with "du'u ... ce'u" and dispense with ka. OTOH, if we need ka to forewarn us of the presence of a ce'u, then we need a new abstractor to forewarn us of the presence of Q-kau.
The obvious candidate is {jei}, it already means {du'u xukau}.
However, I don't remember ever being gardenpathed by "du'u...Q-kau".
