Not a bad idea, but I would not refer to Cruz at all in the speech. I would though, as you suggest, have Trump pledge to scrupulously follow the laws and Constitution of the United States. It should be suggested, quietly and through reliable intermediaries, that Cruz should take that as an opening to endorse Trump and as a lifeline back to getting in the good graces of the party faithful. Make clear that if Cruz did that, the reaction from Trump would be that he was pleased at the endorsement and valued Senator Cruz as an ally and as a man of great integrity.

Works for me.
