What do I need to buy to change bolt pattern
 

I am getting an 06 H2 LE. I want to take the wheels and tires and put them on my wifes z71 Suburban. Its a 6 lug. Is there an adapter I can buy or do I have to buy the whole hubs or have em rebuilt? I know I will need a little boost up to get those tires on but I don't thein I will get a good amount for them if I sell the LE wheels and I do not want them to just sit in the garage. Thanks,
