Changing the task would make it invalid to average measures across users who had performed the different tasks, but in a qual study you aim for insights, not numbers, so you can take liberties that will ruin numbers (which are not your research goal anyway). Qual testing involves a small number of users (58) and directly identifies the main usability problems in an interface. Often researchers will need to use qual methods to supplement quant data in order to understand the specific usability issues in an interface. Its hard to say in the absolute.
