That would have been pretty awesome, especially since RVD and Lesnar had unfinished business from the summer of 2002. RVD got beat badly in the KOTR finals by Lesnar, then RVD (in his hometown at Vengeance) had Lesnar beat, but Lesnar got DQ'd.
Then, within the next two months, each guy wins their brand's championship, and they slowly build the rubber match for RVD and Lesnar.
Would have made sense and would have made for a really nice, well-built Mania feud and match. But Trips going over RVD, Kane, HBK, Steiner, and Booker T in 6 months makes more sense
