Anyone know the diet of Glossodoris sedna by any chance?

Apparently not. I'm sure you've read all of this, which is nearly all that is known about the species:

There is one pic of its food sponge, although it isn't identified.

Oh, ok. Yeah... I have a 180 gallon with 200+lb of live rock and I have sponges growing like MAD! Which is very cool. I might get one Glossodoris sedna as I found one for $10. Might give it a go. 
While these are apparently common nudibranch in their home waters, I would really discourage you from purchasing one, regardless of its cost or the number of sponges you have in you aquarium.
One of the reasons why it is so difficult to pin down what these sponge-eating nudis feed upon is because there are so many different sponge species, so few people specializing in sponges, and it being so difficult to identify sponge species without dissolving their structures to see what they are made of.
If you look at the link that Don provided, you will see that these slug's natural distribution does not correlate with areas with large live rock collection facilities. It is highly doubtful that the sponges in your tank are of the genus and species that this nudibranch feeds upon. What is collected from the wild depends on what wholesellers, distributors, and retailers are able to sell to hobbyists. Personally, I do not think that hobbyists should do anything to encourage the collection of animals which we can not possibly care for in our tanks -- and you can not care for this animal if you do not know what it will eat. Leaving this (locally abundant) nudibranch in the sea will be a benefit for all those sea slugs whose husbandry requirements are unknown and which are not abundant, because retailers take note of what does not sell and will not order those animals in the future.
