Dynamically Change View Column Headings based on Field Value

I have a table, that displays percentages from the previous three weeks;

I'd like to dynamically change the 'Week x' Percentage' Columns, using the value in the 'Week x' Columns to show the below;

This will remove the need for the 'Week x' columns. Is there any way to dynamically change a Field 'Display Name' or Column heading in the view? Note: The filed values are changed weekly using a Scribe Connection and so the Page/Fields are not loaded on change/save? I'm assuming this rules out using Business Rules/JS?

Thanks in advance!
