Interesting poser, thinman... 
On a fretless bass guitar I choose a 2E fingering form as follows: 
E5.... index 
E7.... ring 
A7.... ring 
D7.... ring 
 
Otherwise intonation suffers - especially if this is to be used as a repetitive riff... 
I tried sliding the index along the E string and then barring the 7th fret with it but i broke into a sweat...  
The above fingering maintains the OFPF position for Bass Guitar fingering (Simandl is another animal...) 
Trying to stop each note with different fingers, like a guitar chord, twists my wrist and may invite RSI... 
Normally, when practicing fourths in the major scale I would use the pinky... 
I'd need to know the rhythm figure to be sure... 
 
Another option would be to change fingering from the 2E form to the 4E form... 
|------------------------2------------- 
|---------------------2----2----------- 
|------------------2------------------- 
|---------------5---------------------- 
but that would be cheating... 
 
I'm partial to this sound, though...
