Probably not, but...
An "object" is a discrete (i.e. countable and not consisting of other objects), inanimate (i.e. not a creature) thing (5e SRD). Counting something made of liquid as an object would at best strain that definition, and probably wouldn't qualify, hence why I'm suggesting that RAW this is a no. (Note that if you are OK with calling a sphere made out of water an object, this could work - the sphere is Large but not Huge, so in that sense it qualifies, but it'd be a bit unclear if the creatures inside would get a saving throw against the second enclosure (although probably yes)).
However, comboing it the other way round should absolutely work - i.e., targeting one of the creatures inside the Watery Sphere with Resilient Sphere, and in that case the creature would have disadvantage on its save against being enclosed due to being restrained.
