Nlakoumentas, I hear what you are saying about the delicate nature of the SME mat. I somehow scuffed mine and have no recollection how it happened.
I received a mesh-like mat with a previous Clearaudio TT I owned and still have it. I might try it as a means of protecting the SME. It's very thin so I might not even have to raise the tonearm to accommodate the extra thickness. As for the sound quality of the SME TT, I have not wanted to change the mat, but protecting it has become a concern. Good luck in your quest.
