The north-arrow macro is currently not easily customizable at all. You have to add the following to the layout code metapost def s_northarrow_SKBB (expr rot) = T:=identity scaled 0.7 rotated -rot; thdraw (-.5cm,-1cm)--(0,1.5cm)--(.5cm,-1cm)--(0,-.5cm)--cycle; thfill (-.5cm,-1cm)--(0,1.5cm)--(0,-.5cm)--cycle; enddef; with values .5cm, 1cm, 1.5cm replaced by larger values.
