i think the best way is to find out if the diameter of the 2.0 cdti maf sensor and housing are the ame as the 1.6 turbo pipe

then you could ether use the maf sensor from the 2.0 cdti or put your maf sensor from the 1.6 turbo
in the housing from the 2.0 cdti then you can add silicone pipe and the cone
only guess work but i think it is the best bet to mount the maf safely and correctly
it is strange there are no kits out there as yet apart from the 1.4 turbo
i really have not seen anyone do it as yet just talk about doing it
shorty is working on it may be worth asking were he is up to
