They need a Wario cartoon, simmilar to Phenias and Ferb's more "dramatic" 30 minute episodes, with some Mustache puns, and Warioware humor put in, "Warioware stinks" could be the name of the show, it could revolve around Wario's plans to either scam citizens, or gain fame, utimately failing unless he considers other peoples input...
...Which he sometimes claims as his own ideas...
...even showing the origin of WarioMan...
...and Wario's rivalry with Captain Syrup, (no doubt Wario would downplay her signifigance, given his personality).
