Is it possible to give engine and tip configuration options in the hanger?
That way a Mk IX for e.g. could have LF, H, and HF versions with clipped, normal and extended tips without having to add extra models.
I.e. they'd all be available under the current IX.
Same would go for the V (LF and F) and VIII (LF and yup there were a few HF VIII's).
Yet the model choice in the hanger would only be what it is currently. (I, V ,VIII, IX, XIV, XVI). You would just choose whether you wanted an LF, F, or HF version.
Only concession would be if you wanted for example an HF Spit you had to take extended tips, not strictly historically always happened, but would make thing easier from a coading point of view.
Would also help prevent the "Oh no not another Spit" complaints.
