I remember an Hermès VIP member here who said, some 10+ years ago, that the rarest combos are croc + toile. During that time, they said that it was so rare that it was only offered to VVIPs, most of whom were in Japan because there were so many VIPs in Japan that they needed to be ranked. And only those at the top were offered croc + toile bags, either via SO (there was no a la carte back then), or just as a regular offer when some are made.
If I remember correctly, they said the reason that it's rare is because if you look at where the croc is cut to make way for toile, that's where the good parts of the croc are--prime real estate, if you will--and it will just go to "waste". There was no petit H back then or touch bags, so it could have indeed gone to waste.
I found this picture yesterday from a reseller's account and it reminded me of that member. It's the first croc + toile combo I've seen in years, so I guess it's still rare these days. Also so cute that it seems to be lined in nata or craie or whatever cream color that matches the toile. There's no horseshoe stamp so this could've been an LE.
