Day 4: actually look around Wuerzburg, visit Rezidenz
Day 5: early morning departure to FRA
I'll consider putting in Rothenburg back into the itinerary ... just need to figure out how to squeeze it in.

You can certainly squeeze in more stuff without it getting stressful.
On day 2, I guess that you're going to the
Wertheim Village, which is nice, but certainly not an all-day activity. What you could do in the afternoon is visit the city of
Wertheim and or the city of
Miltenberg, which lies 29km to the west of Wertheim.
If you're only interested in fashion, there's also a smaller outlet in Muensterschwarzach (28km to the east of Wuerzburg), which hosts factory stores of
s.Oliver and
Rene Lezard. You could easily do that on the morning and then drive 80km to
Bamberg, which is great for sightseeing.
On day 4 you should definitely visit the Residenz (as you already plan to do) but add the
Fortress Marienberg as well.
If you need more tips on what to do in Wuerzburg and its vicinity (I grew up in that region) or in Frankfurt (I live there), just ask.
