I think I understand what you are asking here, but let me say it a different way to see if I have it right. You are looking to have people available to work as two different types of roles during different points of time in a project. And, you are not performing capacity planning by role, but by person. So, if that is the case, the percentages you are assigning to a user do not really apply as you will not look at the resource planning tools by role. Therefore, a best guess percentage will work, as long as they sum to 100%. You can then use the team views and staffing views within the people area of Workfront to determine the loading of a named resource either by hours or sheer number of blocks beside a single person. And your assignments will be easier as your roles will help you down select to the people that are allowed to perform a given task in a template or project (via role). I hope this helps.
