Yes I found numerous pics of the FTB Kit, but apparently there is one or two of the Shackleton installation. Someone posted a pic of it but do you think I can find it again --
EDIT: a bit later --
Found this, just had to juggle the search phrase --- In that Shackleton website, it says that the MR.4 would have had leading edge radiators between the inner & outer nacelle (which is where I got the idea for my Nottingham [bottom pic]), so the Nomad nacelle would possible be quite stream-lined with a large air intake under it for the exhaust turbine (sort of thinking like an early P-38 in style).
EDIT: even later --
If you look carefully at the Nomad installation, you can see a portion of the leading edge radiator ---
