Can the 06/07 realistically be made to a 7 seater?

[Badace]

My Wifes Dad passed and left us a Yellow Z71 truck. I sold my truck to keep this for her because he had little else. After 2 years I can not take the color anymore. I want to get her an H2 and I am begging to get rid of that truck. She said ok as long as I get her a yellow one. I am thinking 06 is the last year for yellow but maybe 07. My question is Can I have a 7th seat put in without a lot of fabbing? Can I take a 3rd row seat from an 03-07 and have it fit or is there not enough room? (I have 4 kiddos, my wife, and myself fills it up) I need one more spot for Granma. Thanks,
