Unfortunately, no.  That's one of my top wishlist features.  If you
want to read elements delimited by anything other than \n you have to
use a loop.

files=()
while IFS= read -r -d '' file; do
  files+=("$file")
done < <(find . -type f -print0)

read -d '' is another undocumented feature.  It means use \0 as the
delimiter.
