Ok I finally see what y'all are getting at with the rule wording.....
What about 6-1-7 "R can take the ball at spot of first touching...... or may choose to put the ball in play as determined by the action which follows first touching." If K downs the ball before it goes 10 yards, it's R's ball there at the dead ball spot. It's also a spot of first touching, but for R's purposes for this case play they enforce from dead ball spot. The action that followed first touching is a dead ball after a free kick that didn't travel 10 yards.
Well personally, I would fix 6-1-6 instead of 6-1-7 (I didn't quote the right rule number in previous posts).
Something like...
"If any K player recovers or catches a free kick, the ball becomes dead. It belongs to him unless it is kick-catching interference and R chooses an awarded fair catch or unless
the kick is recovered before it crosses R's free-kick line untouched by an R player. (etc...)"
The "it is first touching" is deleted and encompassed by 6-1-7 to avoid confusion.
