British MRAPs

This is a follow up to my earlier post on MRAPs I am looking to add the Mastiff;Ridgeback and Wolfhound
now the questions
Can the Mastiff and Wolfhound be built form the Meng 6X6 Cougar
and can the Ridgeback be built form the Panda hobby 4X4 Cougar
now for the color are they in US CARC 686A tan or British light stone
any help will be appreciated
