I don't think we'll be allowed to choose our Random Boosts because of two reasons: it would defeat the "Random" part, and DevSisters wants you to spend your Coins more so you'll play more and thus increase the chance of buying Crystals from them.

Besides RNG is RNG. Sometimes you'll luck out and get the boost you want right off; sometimes you'll need to spend thousands of Coins. It's just the way how RNG works.
