Definitely sounds like a good plan. Since Monday, I've been unofficially Australian, anyways, and I can verify it's been fun so far. I just had one disappointment:
World 4 Spoiler: There's a spot inside the fortress in the middle of the stage that takes a mini-mushroom to fit into. I walked in expecting a path to the canon, but instead, it was just a small handful of coins!
Also, info on the Penguin suit! It's a complete upgrade of the Ice Flower in every way. There is nothing you can't do with the suit you can do with the Flower, and the suit can slide. Sliding, as far as my experiences go, can allow you to do many things, like slide across water and even through some enemies. I slid into a Piranha plant in the ground to experiment, and rather than taking damage, I bounced back. When sliding into blocks, you break right through. Additionally, the Penguin suit moves freely under-water, in the direction you press on the D-pad. Ice balls can freeze enemies under the water, where they float, but watch out! Some enemies can break out of the blocks, especially if they have spikes!
