Hi E2e4,

No. Firstly, ‘let us’ should be contracted. The use of ‘let us’ (uncontracted) sounds far too formal for this sentence. Secondly, the preposition ‘at’ sounds as if you are talking about rolling a real ball at a real thing. In other words, it sounds as if you are NOT using an idiom.

However, you can use ‘on this’ (as Bev did in her post).
