Here is 2 SSD M.2 accessories to your reference.
In Jerry's june report, there will have a plan for M.2 SSD converter.
I don't know if it's a good idea since there are already a lot of M.2 converters in market and the prices are cheap.
But maybe we can consider to add a cooling function to our converter because visibility the heat issu is a seriouse problem for PCI Express SSD.
It might be a sales point for our converter.
