Use it as it sits, it's very simple to just get some fancy screws and some nice weatherstripping and simply screw it to the top after both are painted. Not messy and looks great.
For some reason there is a general opinion that folks need their hood scoop to "look factory" which is so stupid it makes me want to punch them in the nards, there are so very few factory scooped cars that nobody in the world is going to give a crap one way or the other about it screwed on nicely or welded on...
