[tlhIngan Hol] nom {-qu'} combination

We have the {nom yIghoSqu'} "maximum speed", as an example of combining the {nom} and {-qu'} in order to produce the meaning of "maximum". However the {-qu'} is a rover. So, if on the verb we have more than one suffixes already, then where do we place it ? If we want to say "quickly they are able to corrupt him", then what would we need to write, in order to produce an effect similar to the {nom yIghoSqu'} ? {nom luqalqu'moHlaH} {nom luqalmoHqu'laH} {nom luqalmoHlaHqu'} Which one of the above should someone choose ? ~ nI'ghma
