What if Hoster Tully had been healthy by the time of the novels ?

Tbf, it was a poor's decision because Edmure was likely having a different info than Tywin. I doubt he was expecting the total war because he was not expecting Robert and Ned to fall.

This is part of it, absolutely. He also had to deal with the possibility that he, not Tywin, would be viewed as the aggressor. Take out what we know Tywin actually did, and a Tully kidnapping a Lannister in the Riverlands followed by a Tully massing an army on the Lannister border might appear pretty aggressive to non-readers of ASOIAF.

Sending Lords Piper and Vance to defend a single defensive line at the border between the Riverlands and the Westerlands was a very bad move, knowing the lack of entranchements and fortifications and numerical inferiority of the Pipers and Vances against the Lannister forces. 

A defense-in-depth with them harrassing and delaying the Lannisters while the rest of the Riverlords assembled their forces and chose a favorable defensive landscape for battle would have been a much better strategy.

Take, for example, Edmure’s choice of not concentrating everything at the Golden Tooth. Wrong? Well, as it played out, yes. But we only know that in hindsight. What if instead Tywin brings the bulk of his forces up through Deep Den or along Ironman’s Bay…those forces massed before the Golden Tooth are in immediate danger of being surrounded, and at best pull back. Etc.

 

It was predictable that it would fail. it was the result that Tywin wanted and Ned was able to see the fault on Edmure's actions the moment he heard of them.

And that may be precisely what Lord Tywin wants, Ned thought to himself, to bleed off strength from Riverrun, goad the boy into scattering his swords. His wife’s brother was young, and more gallant than wise. He would try to hold every inch of his soil, to defend every man, woman, and child who named him lord, and Tywin Lannister was shrewd enough to know that.

By the way, I still find it jarring that Hoster Tully is around 20 years younger than Jon Arryn.

Yeah, Edmure made a beginner's mistake due to his inexperience and rashness, Hoster would most certainely have been wiser.

yeah... poor Lysa, being forced to marry a guy old enough to be her grandfather.

Poor Lysa is quite debatable, knowing the stuff she did to Littlefinger.
