Hypothetically speaking, if こと is being used as a nominalizing suffix in the following sentence:
その時々の課題をクリアすることに、全力で取り組んでいる間は、何も思い悩んだりせずにすむ。
would the above sentence be able to be re-written as the following?
その時々の課題をクリアに、全力で取り組んでいる間は、何も思い悩んだりせずにすむ。
I'm asking this as I'm certain the こと is only there to nominalize the suru verb, which appears to be made of a noun-suru compound.
