Yes, if you can't find the Original (Goldmund Relief Mat), the next best thing is the Oracle hard mat.
I used to recommend just using another record - under your record - as your mat. I was laughed at, until clearaudio introduced Their record mat, which was (yes you've guessed it), -a blank grooveless record.
The (built in) mats found on SME turntables are also very close to the properties of a record.
PS: the Atmasphere 208 was a wonderful table.
PS2: there's no need to spend 10 years on developing a mat.
