Translation:Don't kill each other!
It would no longer be considered a grammatically correct sentence, but I imagine anyone would understand you. The -chuq suffix is generally the first suffix and the only suffix that can occur before it is -Ha' (and maybe -be' and -qu'). The suffix -Qo', likewise, has a fixed position. The only suffixes that can occur after the -Qo' suffix are the Type 9 (Syntatic) suffixes.
-Qo' gets classified as a Rover, but does not, in fact, rove. It has a fixed position after all Type 1-8 suffixes and before any Type 9 suffix. To quote from TKD (using the digital version so I can't give a page number):
Unlike -be’, the position of -Qo’ does not change: it occurs last, unless followed by a Type 9 suffix. Nevertheless, it is considered a rover because it is the imperative counterpart to -be’.
