You would have to keep them suspended, provide them lots of phytoplankton of a few different species, and then a settling cue once they're competent to settle. As far as the settling cue, it's usually a chemical associated with the adult food, but I don't know that anyone has looked into the cue for this species.
Raising the larvae wouldn't be impossible, but this is would be one of the harder inverts, especially if you don't have much breeding experience. If you're interested in breeding inverts I would start off something like shrimp for which the process is fairly established and then branch out into the more untested species.
