This probably does not help aeromax, but I decided to go the bespoke luggage route and found a guy who makes hand-stitched gun cases and who was interested in branching out into bespoke car luggage.
Together we agreed the format and the colour of the luggage and after a number of trial fittings, the following is the end result. It all fits in through the AeroMax rear windows and this proved somewhat of a challenge, but I can assure you it does work.
As you can see in the last photo, Head Office accompanied me on one of the visits and specified a matching handbag, which fits into the passenger foot-well without difficulty, so she is now fully coordinated.

He is now working on luggage for another AeroMax owner and has interest from a number of others.
Bob is available to make bespoke luggage for any car, he can do Aero 8's and is currently working on luggage for my upcoming Aero SuperSport; in conjunction with the factory using their CAD facilities (the perfect marriage of technology and hand-crafted!).
If anyone is interested in his services, please do PM me and I'll onforward his coordinates, but I would warn you now that hand-stitched luggage of this quality does not come cheap.

P.S. aeromax, he should be able to make what you want to match your existing luggage.
