The name/combo for this hypothetical Sparking Deathscyther would be Penalize/Punisher Deathscyther HJ' 1A. The letter P has surprisingly not been used for the abbreviation for the Layer Rings yet as far as I know, so I think it should be okay.
The gimmick of the Penalize/Punisher Ring would most likely just be an upgraded version of Double Strike, but heavier and using the metal ball system that the Flare Base from GT had, but for Attack Types instead.
However, another gimmick idea could be that the Penalize/Punisher Ring has a "sub-layer" (akin to Arc Bahamut) that locks onto the Chassis prongs, where each lock pushes the Double Strike scythe closer to the main scythe, until the Double Strike scythe is completely locked onto the main scythe, creating more impact and weight focused on the scythe but loses the Double Strike gimmick (until you reassemble it).
If I could have a new Driver, I would love to see them make a Jm Driver (Jaggy Metal), but that would never happen, much like the possibility of this evolution.
