Yes, you can use a trim ring on the bevel-top, like the 2.5
There are two made, a Provari with air slots, and a Svoemesto
The Classic, P3, and Procyon remain a flat top, as does the Radius.
L to R : V2.5 with Svoemesto trim ring, P3 with flat top, Classic with flat top.
If you don't find one let me know, I can probably locate one.
