If it's fluid, I guess you always would have an issue with buoyancy/density. The things you want to suspend will either want to float up or sink down before it cures.
But maybe it could work with something like beads of same refraction index, and then pour resin in when everything is in place? At least it works for water, I've seen it used for decorations and then pouring water over when everything is in place.
