Ropes

Hi All
I am currently replacing worn bits on KIRA and would appreciate some advice as i go along.
firstly i am replacing some rope, the Jib furling drum has some tiny worn out rope, the manual says 4mm white / Green, i would like to replace it with as large a rope as possible as it is easier in the hands. but obviously it has to fit on the drum. has anyone else installed larger rope? and are we keeping with the colours in the manual?
Cheers
