if increased output impedance isn't a problem (comparing to 170/74) , go for it
in fact , often used in output stages of Japanese CD players ( with fancy names for these stages too)
Rout will be roughly (1/conductance)/2 ........... 2 , because they're working in parallel
if you're using trimpot between sources (20R maybe) for fine setting out DC , add 5R to that
