I was thinking of trying it with a sweet desert style dish.

Anybody have an opinion on this?

Thanks.

yes have used wanton wrappers for ravioli just remember to wet the edges I used a beaten egg batter but you could use water.

I have not used them for a desert, but I don't know why not. I have used them with all kinds of filling, mostly meat type fillings. I did do a corn filling once, it was good. CF:)

I have, too. There are several methods to seal but you can also try a cornstarch paste (4 t. cornstarch mixed with 5 t. water).
