Atma-Sphere MA-1 tube rolling


Curious to hear if anyone has tried tube rolling the Atma-Sphere MA-1 or MA-2, for that matter: driver tube vs power tube rolling? Anyone tried replacing the 6AS7G power tubes with either 5998 tubes or 6080 tubes?  Thanks.

6080 mil spec (same tube), should have better element support structures inside, and maybe even thicker glass, could also feel heavier. Which all should make it less microphonic and far sturdier, as for sound difference compared to 6as7g try it and see.
For memory I had them from input 13D3 > as pre drivers >to the 300b> interstage trany > 805 SET monoblocks I had, real massive hot beast of amps
