I doubt the great clans will stand by and watch yukigakure is born. Probably Kuroko will probably have to marry the daughter of the Daimyo of the Snowland, so that the Daimyo that missions in the Snowland are given only to the ninja of Yukigakure. Even better if the Daimyo and any heirs are killed so that Kuroko inherits the Snow Land through her marriage. I know! it's a bit amoral but it has to be done. It would be good to develop the technology to transform the land of snow into the land of spring. Finally the Kekkei Genkai. I don't argue about giving Kekkei Genkai only to ninjas loyal to him, however could he try to get more Kekkei Genkai? Mei Terumi had 2 Kekkei Genkai, so why not try to get some more Kekkei Genkai? Ice is powerful but some other more subtle power would be good. An ocular kekkei Genkai would be very good. Maybe he can try to catch a Hyuga and use his eyes to create the Giro Giro no Mi fruit for himself. the power of Giro Giro no Mi would be really powerful in Kuroko's hands and very useful for governing, thanks to the ability to see people's thoughts. Or capture one Uchiha and use his eyes to create some other Kekkei Genkai similar to the power of the mangekyou sharingan, for example the Kamui could easily be a replica of the Doa Doa no Mi fruit.
