Using WD's Red SSD drives in EX series NAS

I own an EX2 Ultra with 2 mechanic WD Red drives.
I noticed WD had a SSD version for the Red series drives, e.g: WDS200T1R0A.
The hard drive compatibility List for any of My Cloud EX series NAS doesn’t mention SSD drives.
Did anyone try mounting an SSD drive to any of the EX series NAS?
Maybe EX2 Ultra specifically?

Thanks @Mjoelk, very interesting approach.
By mechanical guide you mean the metal that holds the drive in place and prevents it from moving?
In this case such adaptor can be easily made or purchased.
