Sheesh, that was easy.  Only thing is having to chop it up into an array 
again:

Run:

LIST=( one two three four five )
echo $LIST
proxy="LIST"
set -A "${proxy}" "onezies toony threeatlast forlorn fivealive"
echo $LIST
LIST=( ${=LIST} )
echo $LIST[2,3]

... gives:

one two three four five
onezies toony threeatlast forlorn fivealive
toony threeatlast

... I wonder if it's smart enough to accept array output directly?  
Tried a few things with no luck.

Tx.  Bart, would you please give me someplace to read up on " ::= " also 
on the leading colon -- for the previous method.  I have no idea what 
that does but it can't be omitted.
