Get one of Jack's (Kinetic) nose cones, then trim the sides to tilt it forward a few degrees. This will not only look good, but it'll raise the back of the nose half an inch and match the angle of the hood better. You can go as high as 11" at the forward edge of trhe scuttle. 10-1/2" will look better. If you have the nose, you can mock up the scuttle firewall in cardboard, then run tape from the scuttle to the nose to give you an idea of the shape and height of the hood.
Fitting the engine under the hood can be a challenge. A large percentage of Locosts, like about 75%, have at least the air cleaner sticking out, and sometimes the engine. Hood scoops and bulges are not uncommon. The Miata engine can be made to fit a little easier.
Here's my car with Jack's nose, tilted forward, and a 10-1/2" scuttle. Obviously the engine didn't fit, and a future hood scoop is a possibility. That's still quite a slope on the hood. It wouldn't look better with an 11" scuttle, and that still wouldn't get the engine covered. A taller nose wouldn't look any better either.
