There were a lot of forms that were never used. Drive never performed a Tire Koukan with Burning Solar, Colorful Commerical, Deco Traveler or Amazing Circus and out of the 7 Tire Kakimazerls accessible to Type Tridoron, he only used 3 of them.

But you asked for a creative idea and me pointing out missed opportunities is too easy so my suggestion would be Dark Drive Type NEXTridoron, using the same gimmick as Drive's final form with Dark Drive merging with his Mercedes and a Tire Kakimazerl of his 3 Shift Cars. This version would be the real Tomari Eiji.
