We call correctly the Lannisters a dysfuctional family, but this dysfuctional family manages to usurp power in large part due to the dysfuctional relationship among the Baratheon brothers.
If Robert listens to Stannis and Jon Arryn about Janos Slynt, a less corrupt decisive player backing the Lannisters remains.
If Robert and Stannis like each other more then Stannis and Robert cooperate on the incest issue. Renly and Stannis who worry about the Lannisters and both had their own plots to get rid of them (one because of the incest wanted to do so and was gathering all available resources to do so, the other out of fear and he wanted the Tyrells to replace them) I can see them work for that objective.
After Robert's death Renly declares himself king first while Stannis plans in Dragonstone. Until the decisive confrontation that gives Tyrells to the Lannisters and kills Renly. However if both cooperated from the start and communicated, their combined forces, especially with Renly's good relationship with the Tyrells and a Stannis who in this scenario accepts them, instead of fighting each other and each using their advantage (army and red witch) against each other, they would use it against their enemies.
This isn't a particularly novel observation to most of you I know but it is true that a lot of the problems of the Baratheon failures and dynasty had their source not only in particular failures of Robert's kingship (there were those) or the actions of the Lannisters (again played a decisive role) but in the dysfunction of the three brothers relationship.
I am reminded of the scene of the stag and the wolf at each other's throats and I imagine a scene ith two or three stags killing each other as well.
