Don't think it can be done.
The eggs could be isolated in a very light flow area (the crab 'fans' them in the water not sure how you could replicate this.), but the main concern is when they hatch they go through a free floating larval stage which is near impossible to keep. Not only is it difficult to feed them (you'd need phyto, marine snow, green water, something similar to those) but its difficult to keep the tank filtered without killing them.
There's also a likely possibility they'll eat each other during that free floating stage too but that's pure assumption.
Its why we don't have any bred crabs in the hobby, shrimp we can get a formula that works and even then you need another setup dedicated to raising them for a couple months before they become like 'normal' shrimp, crabs are just equally more painful and likely more aggressive to each other.

Sorry for not responding to this earlier OP!
Actually in this case it can be done (though getting the flow just right with a bubbler in a larval rearing tank or in an egg tumbler can reportedly be pretty difficult). Rearing the crabs themselves is actually relatively easy (see the link in the quote below):

The brine shrimp were a good idea, and Tavero’s advice is solid - fed live Baby Brine Shrimp (Artemia nauplii), under proper conditions, Mithraculus sculptus (the emerald crab) should have about a 20% survival rate to settlement. Enriched BBS can raise the survival rate to about 25%.
You can make a DIY BBS hatchery pretty easily, but I don’t know if you’d be able to produce enough/fast enough for this batch of larvaeGrowth, development, and survival of larval Mithraculus sculptus (Lamark) and Mithraculus forceps (A. Milne Edwards) (Decapoda: Brachyura: Majidae): economically important marine ornamental crabs
