It might be easier if one can have a bass player play the lowest note in each of the 4note groups.
WARNING it does not sound typical country
have fun

From a Gmajor scale play from G to B = G A B C# D E F# G A B
mute the strings between each note and move the bar as quick as possible
F#|-------------------------------------------------------
D#|-------------------------------------------------------
G#|-------------------------------------------------------
E |-------------------------------------------------------
B |-------------------------------------------------------
G#|-------------------------------------------------------
F#|-------------------------------------------------------
E |---3---5---7---8---10--12--14--15--17--19--------------
D |-------------------------------------------------------
B |-------------------------------------------------------
Then for every note played add another note 2 steps above from the same scale
F#|-------------------------------------------------------
D#|-------------------------------------------------------
G#|-------------------------------------------------------
E |-------------------------------------------------------
B |-------------------------------------------------------
G#|-------------------------------------------------------
F#|-------------------------------------------------------
E |---3-7--5-8--7-10--8-12--10-14--12-15--14-17--15-19----
D |-------------------------------------------------------
B |-------------------------------------------------------
Then for every note played add another note on the 5th string
F#|-------------------------------------------------------
D#|-------------------------------------------------------
G#|-------------------------------------------------------
E |-------------------------------------------------------
B |----3-7---5-8---7-10--8-12--10-13--12-15--13-17--15-19-
G#|-------------------------------------------------------
F#|-------------------------------------------------------
E |---3-7---5-8---7-10--8-12--10-14--12-15--14-17--15-19--
D |-------------------------------------------------------
B |-------------------------------------------------------
The keen eye will observe that there is 6 different perfect fifth intervals played
and only one tritone(flat fifth interval) and each group of 4 notes outlines either
a maj7, dom7 or minor7b5 voicing

I have not written any specific rhythm. Just play each 4 note in a rhythm that feels good to you.
And for ease of play I have used no pedals/levers and only two different strings
