I don't think that would really be the same thing.  For a botch, you need more 1s than 6,7,8,9 and 10 combined.  For a "hilarious success," it should be more difficult to achieve.  Also, I am good on either "exploding" tens or double successes.  Either works, though double successes results in a higher average number of successes per roll, so that's something for you to consider.
