I would love to read such plot. And the icing for me would be if in their "love development" Harry were even more of a "bastard" than Draco (on the outside) and Draco were flustered by it. Harry could also be resigned to die on the inside (and this and Wisengamot) could be the reason for his "bastardness"). And please, let Harry be the top.
And I'm shutting up and am off to Dreamland...
