Did you consider using mirrored context reports in a smart folder of users?
The parameter for the pivot could potentially be defined so as to include the weekday name I believe.
Have you considered a board view, where the columns are the dates (you would need to use some kind of auto-linked database of date entities) and the rows are projects (and each card can show the time spent and the person)?
Or the rows could be people (and each card can show project and time)?
Or you can use mirrored context filtered boards (per project or per user)…
