You could use this for your search string "\((\)\S-"
Then use (replace-match "( " nil t nil 1)

Like above, using "\S-\()\)" and (replace-match " )" nil t nil 1)

If you use skeleton-pair for your parens you may want to look at
rgb-doublespace-maybe on www.emacswiki.org
It puts 2 spaces with the cursor between them if you type space
after typing a skeleton pair.  So (_ gives you (_^_) where _ are
spaces and ^ is the position of point.
