Given that the bottom E and A are two octaves higher,a .010 and .007 will tune to that. The middle two, one octave higher, will need .014 and .008, and the top two, as standard can be .012 and .010. All I've done is calculate each string as a close approximation to a standard open guitar string, given its open pitch. These can be changed by about 10% either ...
