It would be awesome to retime the Lucid objects if that is possible! Especially since Lucid is a unified solver with Softbodies, rigidbodies, fluids, etc all interacting!
Coilbook has given two links. The top one is showing the Rayfire Timescale property - this is where Rayfire is slowing down time Realtime - while the simulation is running. This is a great effect but it makes it hard to iterate and the results are permanent.
The second video is showing the RF Cache tool, where the simulation result is being slowed down and frames interpolated.
With Lucid we can get similar results to video #2 (for dynamic objects only, don't see this working with fluids?) using the Alembic Playback graph (Max 2016).
With the paintball splashing into the wall.
Lucid can support initial animation, as seen in this video:

If it's not working using only a fluid sphere (the paintball), One method to achieve this could be:
-have a rigid body sphere which is animated into the wall. This Rigid sphere is a collision object with its normals facing inwards.
-Use the time range feature to turn off the sphere a few frames before it impacts the wall.
-Now position a lucid fluid sphere inside the rigid body sphere. It will be encased by the collision sphere and then the moment the collision sphere is removed from the sim, the fluid will inherit the motion of it, and collide with the wall.
