I'm also very curious about this question, I'm trying to figure it out in a similar scene.

Hello people!
I know this is an old post but I found out one way to make “fake collision.” I have been doing a boat simulation and wasn't allowed to use a flip sim because of speed and resources. I struggled quite a bit to find a solution to make the waves collide with the boat. But here is my solution to that
What I found out was that if you select and area and change the attribute of conservation or wavespeed to 0, then the ripples will collide with that area. So it's like a cheat way. But if your object are moving it's not enough to just plug it into the rest grid or initial grid. You need to do this with sop solver in dops. Entagma has a tutorial how to create ripples with a sop solver. I created a group of points and then put down create attribute node after that one and selected the group to make that have 0 conservation.
I hope this maybe can help a troubled soul
