I don't see how this would be possible. The LS block is 81mm bore and the H22 head is made for a 87mm bore. Also, the head bolt spacing is about 3/8" wider on the H22 then a LS (I just went and measured both heads). The H22 head is longer also. I don't see how DH made a b16 work on an H22 and don't know why you would not just keep it all H22. I understand being different but you will spend stupid amounts of money to get beat by a turbo D16 but I guess you could always say you are different.
