WI Peru and Bolivia reunited following the War of the Pacific?

What if, following their embarrassing defeat against Chile in the War of the Pacific, Peru and Bolivia reconsidered the concept of the Peru-Bolivia Confederation?

 

Any ideas?

 

The problem it´s that both countries were highly unstable after the War of the Pacific, in fact Lima was occuped by Chilean Forces until 1883, and Tacna and Arica were occupied territories until 1929, and Chile manitained in this epoch A preponderant weight in the exterior an interior politics of Both countries until circa 1920, and considered any proponent of said Union as an aggressive movement. So the only moment you could consider a New Peru-Bolivian union (or Peru-Alto Peru union) is after 1930, but by this epoch both countries have their national ethos formed.

Maybe after the War against the Confederation is a option. but not after the War of the Pacific

 

There WERE talks of it, but I am not too sure how'd that work out.

Besides, last time we tried, we kinda got our asses handed to us by Argentina and Chile.

I suppose it could be done, but it would lead to a massive Civil War that WILL result in Chilean intervention.

However, if this also leads to a Guerrilla war, a chance could happen of Chile being bled dry to exhaustion while warring in the Andes...
