Looks like a sed looper problem, find a space+not-space between 6 and 15, and change it to a not-space space, and if found, try again. Looping sed is not so fast, but when you need tight control, you cannot do too much at once. It's a bit like a bubble sort:
Code:
sed '
  :loop
  s/^\(.\{5\}[^ ]\{0-8\}\) \([^ ]\)/\1\2 /
  t loop
 '
