Flight coffin for 2x XDJ1000 and DJM900 Nexus 2

Hello,

Looks like there's no adequate forum section for my question so here itit is in the closest alternative.

I am struggling to find a flight case which will house 2x XDJ1000 (combined weight 3.3kg) and a DJM900 NXS2 (8kg) - that fits into 32kg limit for a baggage item on flights.

Closest I got is a Gorilla case that weighs 17.5kg, bringing a total weight to an impossibly close 32.1kg! Talked to airline and they are not forthcoming for that extra 100grams.

Any ideas, recommendations or experiences with this setup and flying around?
