The result you're looking for looks really custom to me. That is to say, I don't know of any built-in PHP array functions that would do that. However, I did write a custom function for you. Warning: it is very tailored to this occasion and thus probably not very reusable.

function cust_array_merge(array $array1, array $array2)
{
    $merged = array();
    // loop through main array
    foreach ($array1 as $key => $val) {
        // check if $array2 has the same index
        if (array_key_exists($key, $array2)) {
            // reset $array1's indexes to $array2's values
            foreach ($array2[$key] as $subKey => $subVal) {
                if (array_key_exists($subKey, $array1[$key])) {
                    $tempVal = $array1[$key][$subKey];
                    unset($array1[$key][$subKey]);
                    $array1[$key][$subVal] = $tempVal;
                }
            }
            $merged = $array1;
        }
    }
    return $merged;
}
