For enjoyment, and club meetings, themed build-offs, Yes and Yes.
For contests? I'm afraid you are stuck with the Bf109 and FW190 and Tiger and... creativity doesn't give any bonus points in most of the competitions that I'm familiar with, regardless of the category it's about...build quiality, then your competition, and then reference (note as distinct from accuracy, references is required, accuracy is totally...subjective given the judge). How it works is like...the judges need to know about something before they can award points - the point structure works like the more they know the subject you are doing, they more favourable your entry is, because it's 'easy to judge'. And...truth be told a judge is not going to read your 20 page reference manual, they'll look for faults first (because it's an unfamiliar subject) then only when that fails, belately flick through the reference to award you some points.
Some of the more creative ideas I've seen include, a plated dish of 'egg (planes)' with bacon, a choice of 'straight boiled' (OOB) and 'scrambled' (ie eg planes with parts mix matched). And no, it did not place, because there are perhaps no points awarded for creativity.
