The fact it looks a little like a B-2 shouldn't suprise anyone. Stealth technology is bound to dictate that. If certain things make a plane harder to spot, then that's what you use, so we end up with a sort of convergent evolution in design terms.

Not neccessarily.
That's up to the materials you're using.
As long as the main parts of an aircraft's fuselage are made from materials reflecting radar signals, you're right.
On the other hand, an aircraft made of pure composite materials, which themselves are designed to let radar signal pass by, could look like whatever it wants.
