<p>For the first one it should be "would" not "will." I understand why you'd use subjunctive for desire in Spanish but I don't even know what the "subjunctive tense" is in English. You're overthinking it. The second one would be "would" also, I suppose.</p>
<p>"I desired that you ___."
This is semi-awkward. In most cases, desired doesn't have a noun clause ("that you do your homework") after it. Verbs like "wish" and "hope" are more commonly used that way. Also, the "that" is not necessary and often omitted.</p>
