I know how to do a better version of the sonic. Take a lightsaber hilt, put the end with the four little things coming out, then put a light green stud on it. If it's for the 11th Doctor, use a black hilt. If the 9th or 10th, use a light grey hilt and dark blue stud.
Oh, and here's a Batman decal.
And I agree with jedikermit. Han Solo's legs would be better.
