The Pacifistas use a reproduction of the Pika Pika no Mi's effects, not the fruit itself.

While I think the Goro Goro no Mi's effects could probably be easily replicated, the Marines aren't aware of Enel or his abilities, so that's unlikely.

And although I believe some kind of freezing effect could be replicated, I highly doubt that magma is something that can be reproduced, as the only other place it occurs besides Akainu is in volcanoes.
