I ended up making a milk- and egg-free chocolate mousse that actually turned out OK. I compromised my principles and used non-dairy whipped topping and melted mini marshmallows instead of cream and eggs, but it was good quality chocolate so that made it edible. Accompanied by pistachio marzipan "eggs" stuffed with dried sour cherries (that looked more like olives with pits!), dark chocolate bunnies - just a shell made in a mold, no filling, and strawberry sauce that I happened to have in the freezer. Flavors were nice together, the mousse was soft and fluffy so I served it in a quennelle instead of my original idea of cutting a shape, and my SIL who is allergic to everything and is the reason I made this wasn't feeling well so didn't come. Oh well, always good to have a challenge to test the ol' skillset.
The rest of dinner (cooked by Mom and brothers) was grilled lamb with chimichurri, rice pilaf, grilled asparagus, roasted carrots, butter lettuce salad, and lemon pot de creme. All delicious.
And apparently the Pope says there's no Hell, so that's a relief. 
Happy Easter and Happy Equinox!
