You can play those exact same notes in the open position using the open A string.

Anders does it in this lesson in the Blues 1 style course.

You could also just play the whole thing an octave higher where the frets are closer together.  Same basic sound but higher on the fretboard.

|-12-12-12-12-12-12-12-12---------|
|--------------------------------------|

Alternately you can play just the A note an octave higher.  So instead of playing the A note on the 5th fret of the low E string, play it on the 7th fret of the D string.  Barre across the 7th fret on the A and D strings.  Include the notes E & F# on the A string and you get this.

|-7-7-9-9-7-7-9-9----------|

Same basic sound but slightly inverted and easier to play.

Finally, keep working at playing it as Anders does.  You might find these exercises on increasing finger strength and dexterity helpful.
