Sting - I would have him go back to his white crow facepaint and run hero Crow Sting vs Satan Taker. Imagine WWF Champion Ministry of Darkness Undertaker feuding with Sting as he goes through the Ministry week to week to the Royal Rumble. Then it's Sting at like 22 in the Rumble and he has to get through the Acolytes and Viscera in the final 4 to get to Mania! Whoever wins, wins but you still get the dream match. *Yes, The Minstry came in late 98, but this is wrestling, we control the timeline*
Goldberg - Again, put him vs Undertaker. Unstoppable Force vs Immovable Object! Who blinks first. After that, you can have him vs Kane. A god vs a monster. And for the sake of "match quality" these can be non-title feature bouts. Fukk star ratings, give us chokeslams off the stage, spears through barricades and cage walls, lightning not phasing Goldberg, Taker gets buried alive and Kane gets set ablaze! Make Goldberg a machine!
Scott Steiner - Imagine an unleashed Scott with less censorship and NO DROP FOOT! Still has the explosiveness but also has the mic skills to work in the Attitude Era. Peaks and freaks! Frankensteiners! Suplex City! Steiner Recliners! Lead pipes and chainmail! Imagine the shyt he and Rock would say in a 10 minute promo!
