Here's another awk solution (different strategy, and slightly shorter when compacted - Update: this reverses every line, and if your's did the same, i.e, without the END block, it would still be shorter than this...oh well):

#!/bin/awk -f { for (i=1; i<=NF/2; i++) { t=$i $i = $(NF-i+1) $(NF-i+1)=t } print }
