If you get no response in here, it's prolly cuz no one has tried it yet.
Where I live, one of the home centers sells plastic laminate "handipanels". They're made 2 foot wide by 4 foot long pieces of laminate cut from damaged 4 X 8 foot sheets, and cost $4 each.
I'd suggest buying one of those and trying to paint it with a brush. Thin the paint and paint with a brush. Try a foam roller, and a nap roller. Try painting, then back rolling.
Really, what you want in a paint for a working surface like a counter top is high hardness. The harder something is, the less it will be scratched by sliding things across it (or by cutting something on it with a knife, and people still do that on counter tops).
So, if you can get a real high hardness out of this paint, and a reasonably smooth attractive finish, it should work well on a counter top or any other working surface (like a window sill, shelving, chimney mantle, floor, etc.
It's common to find people asking about painting laminate
