Yes that's not a problem, the only flaw is I don't think you can change size of area where radar map displays so you either have to have a squashed version in that or one that only uses middle section of display so is quite small.

(also if you every get that far - beware there is a maximum height for radar maps - don't know exactly what - so you can't necessarily make one to the same size as your regions as scriptorium guide suggests!)
