A Double Dragon with the Guilty Gear graphical technology would be great
Problem with that, though, is that the Guilty Gear Xrd/Strive look (I assume that's the GG you're talking about) isn't powered by technology so much as it is hand-done work. Those 3D GGs are treated like keyframed cel animation using a live game engine; they go in by hand and pose the characters, move the lighting, and adjust the shading and effects for each controlled frame of movement. Characters are distorted and relit to look right in a flat view. There's no global illumination or motion tweening, instead much of what you see was posed that way by a person.
(*At least, that's the Xrd approach, I'm not sure what changes Strive made to the workflow.)
This way of 3D-as-2D works in GG because it is handled as a flat, side-on game. All the things which make a modern action game dynamic and varied are a problem for this system. The GG "technology" fails to work if the player expects the camera to be controllable at any point. There also can not be much of physics interaction because the game depends on predetermined movement rules. And exploration and level variety is limited since characters can't reflect most lighting changes or adjust to terrain.
A 2D sidescroller would make for a cool Double Dragon, if that's their idea of a "3D revival", and the GG method could work for that. (Ark Systems did 2d GGs in the past with its sprites, to varying degrees of success. ) Otherwise, this isn't going to work, there's no special engine to make more games looking like Guilty Gear.
