Is it permissible to supplicate that a person's vision be contingent upon the realization of good from this vision?

The Sunnah for someone who is contemplating a matter or is unclear about the best course of action is to seek guidance from Allah the Almighty through the supplication (du'a) reported in the Sunnah: "O Allah, I seek Your guidance [in this matter] by virtue of Your knowledge, and I seek ability from Your power, and I ask You of Your immense bounty. For You are able and I am not, and You know and I do not, and You are the Knower of the unseen. O Allah, if You know that this matter is good for me in my religion, my livelihood, and my ultimate destiny, then ordain it for me. And if You know that this matter is evil for me in my religion, my livelihood, and my ultimate destiny, then turn it away from me and turn me away from it, and ordain for me what is good wherever it may be, and then make me content with it." One should then state their need.

Indeed, the supplication mentioned in the question contradicts the established Sunnah regarding Istikhara. Therefore, if she supplicated with it and saw the person or did not see him, that would not indicate the goodness or lack of goodness of the matter.
