Well you'll just have to look at history, such as
Psystar case, which Apple sue to extinction. As long as your company have $100billion in dispose and a team of lawyers to fight in court with Apple, then I think it may be possible, but I still think Apple will still win since they have a better case, it's a closed source OS that they own.
A better idea is to buy a country and then have laws that disregard all Apple legalities, then create third party devices that will be able to run iOS and sell/allow that device to be used in that country.
However, if you want to install Mac OS to a PC, that is possible, it's called Hackingtosh.
Personally, I think iOS is very limited, the more you learn about about Android you will find you don't need iOS, even when it come to simplicity and design. You could check out phones that use MIUI interface, such as Xiaomi. MIUI have a theme engine and there are many excellent themes available, some looking similar or exact copy of iOS. MIUI also emulate some of iOS design such as icons on the home screen and overall nice look. Some details here:

You could use Android launchers that emulate iOS like iLauncher, but MIUI is a better solution since the whole OS design reflect some iOS concept while still having the freedom of Android. Also because a lot of these iOS launchers tend to come with adwares or spywares.
