You can always do fancy reformatting of text with awk:

    uptime | awk '{
        if (match($0, "days,")) {
            today = $5;
            sub(":.*$", "", today);
            hours = 24 * $3 + today;
            sub("[0-9]* days,[^,]*,", hours" hours,");
        } else {
            today=$3;
            sub(":.*$", "", today);
            sub("up [^,]*,", "up "today" hours,");
        }
        print;
    }'

The above should work for both types of uptime output.
