I haven't gone through the trouble to do it. I haven't really used C3, but it's capabilities are roughly the same as C2.
There are three parts to this:
1. Have a list of points to define a polygon. Then we can do the logic in the previous post to do the splitting. We wouldn't be working with actual Construct objects. So probably use arrays to store this stuff. This is math and algorithm stuff, which is doable depending on your skill.
2. We need a way to draw these polygons. Construct doesn't have a way to do this. There's the paster object I made for C2 that has a "draw quad" action. That could be used to draw any polygon with some creativity. You'd have to deal with texture coordinates if the split objects have textures. The paster plugin was ported to C3 by someone, but it won't work with the new runtime at all if that's a concern.
Alternatively you could just use sprites stretched into lines to do the outline of the polygon without third party stuff. The con is the polygon wouldn't be filled.
3. Physics. The built in physics behavior is unusable for this. I don't think any of the third party ones are either. You'd either have to deal with another physics library directly in javascript or implement the physics in events. It's going to be a lot of effort either way.
So more or less everything from scratch, plus most of it wouldn't be able to interact with other construct features. So construct doesn't really have anything to assist with making such a game. This safely throws this into the very advanced difficulty range.
