I use this turnaround to specifically "illustrate" the jazz addage of "...hold two, move two..." First I have the students first play the standard chords: E7 (fret5), C#7 (fret 2), F#m7 (fret 2) and B7 (nut) to get the feel and sound of the changes. And, then, I show them how to play the same thing at fret 7 with absolute minimal hand / finger movement! And, the only change made is an extension of the C#7 chord to a C#9 chord (see below).

As "homework" I have them practice all 10 examples. As classroom exercise, I have them improvise over the last (10th) example. While certainly more jazz than blues, your 10 examples are nevertheless an excellent "bridge" for learning how to "...play the same thing..." ten different ways.
