Yes, you can get someone who is a pet class to help you train away the seahorses. Then you can swim down, grab the bones and WC cap out.
This thread discusses the strategy in more detail:

Another option is to invis down there by yourself, then pop DA idol (or cast DA if 55+) so you can grab the bones and cap out with the seahorses beating on you. This kind of requires you to know exactly where the bones are.. I verified the location of the bones on the EZserver before I went through with this method.
