I can't claim to have tried it but there are recipes for vegan chocolate mousse using avocados:https://chocolatecoveredkatie.com/avocado-chocolate-mousse-vegan-healthy/However, that doesn't help use the liquid left over from chick peas. I know people who claim to have successfully made meringues using aquafava but, again, not tried it personally. Their advice is it takes a while with an electric whisk to get it to a suitable consistency.
