Possibly. Essentially, it depends upon how fast you play the Liszt C minor exercise. If you play it as fast as you intend to play the Revolutionary, absolutely. In some ways, Op. 10, No 12 is easier, because you can blur the notes a lot more, and don't need to play with so much clarity and accuracy. In fact, a somewhat imperfect performance of that etude is actually more convincing and effective. But you also need to have the 'spirit' to do it- which I guess you have, since you want to play it!
Yes, once you get the studies of S136 down well, so that you can play them clearly, accurately and quickly, you will definitely be ready for the Jeux d'Eau, at least mechanically! In those early studies, Liszt had already laid the physical foundations of his technique (i.e. finger strength and independence)
