I don’t think it will work very well. Nothing adheres particularly well to ABS and the paint thickness will interfere with the fit between blocks. It’ll chip off at all the contact points.

Second point I'll give you, but it's perfectly possible to put a good paint job on ABS, and one or two of my second hand Duplo bricks have no-prep rattle can overspray on them which is proving extremely durable 🤨
Come to think of it, maybe I’m mixing my plastics up. Doesn’t ABS go a bit soft and stinky when something like cellulose goes on it? I’m thinking styrene kinda stink.
