Yeah, x seems the most appropriate candidate. It sufficiently rare in English to not trip people up too much, from a cursory glance at Wikipedia it’s at least used for that purpose in Pirahã, and it even looks like a little pictographic “stop” symbol.
Edit: Oh, apologies, I completely misunderstood the part where “ņ” was actually written with the letter “q”. Nevermind that part!
