It is crucial to the requirements in that it specifies that
H is required to predict
(a) The behavior specified by the finite string D

 Which must include *ALL* of the code of the PROGRAM D, which includes ALL the code of everything it calls, which includes H, so with your system, changing H gives a DIFFERENT input, which is not comparable in behavior to this input.
 

(b) As measured by the correct partial simulation of D by H

 Nope, by H correctly predicting, with a partial simulation of D by H if possible, if the COMPLETE simulaiton by a "hypothetical H" replacing H but not changing the input, would never halt.
 

(c) When H would never abort its simulation of F

 Which, since that isn't the case, put you into the realm of fantasy.
 

(d) This includes H simulating itself simulating D

 Right, H must CORRECTLY predict the behavior of an UNABORTED emulation of its input, and if, and only if, it can determine that such an emulation would never halt, then it can abort its emulation.
 Note, that is the emulation of this exact input, including D calling the ORIGINAL H, not changing to the Hypothetical, since by the rules of the field, the input is a fixed string, and fully defines the behavior of the input.
