Succulent ID

[plante1234]

Hello, can anyone help ID this succulent? It is similar to a Burro's Tail, but cannot seem to pin point the exact variety. Photo attached.

Wild guess: Sedum clavatum

My best guess is that it is an intergeneric xSedeveria hybrid with Sedum burrito as one of its parents. It could be Sedeveria 'Blue Burrito'.

There is a possibility of it being XSedeveria 'Silver Frost'. Here's a pick of my specimen.
The leaves are more obovate than XSedeveria 'Blue Burrito', which seem relatively more narrowly pointed compared to the former.
Sedeveria 'Blue Burrito' hybrid succulent is a cross between Sedum morganianum and Echeveria peacockii, seemingly inheriting the more elongated leaves of Sedum morganium.
Just a thought...
