If you leave the original 2.5mm supply wire to the relay, the battery will
charge slower.  If you change to 6mm the way VW did it, you *might* shorten
the life of the relay, in which case you could replace it -- however rumor
has it that the existing relay has a fairly hefty rating.  The Hella kit
makes sense if there is not already an installation (and if you look
closely at the label on the Hella kit, I think you'll find it says
"fridge/aux batt" or equivalent).  I don't know what size wire Hella supplies.

Absolutely.  A parallel arrangement that would let you actually start from
the aux battery would involve starter-size cables and monster switches.
