How plausible was Bolivia being part of Argentina after independence?

Most of Bolivia's territory was once part of the Viceroyalty of Rio de La Plata. In some Argentine wanks, the entire Viceroyalty remains united after independence (like Gran Colombia or the Mexican Empire). But I can't find much info on this idea. The Peru–Bolivian Confederation is a much more popular idea in AH apparently.

How likely was Bolivia being controlled from Buenos Aires? Was there ever a chance for that to happen after the May Revolution? Could such union last?

I see Argentina staying with Paraguay and Uruguay but not with all of Bolivia, what they could have done is take more territory during the war to end the Peru-Bolivian confederation.

Elites of Bolivia and its people want like independence. Iirc Bolivar even thought they would either be part of Peru or Argentina but they chose to independence. Mainly iirc cause of silver mines and others.

The border between Bolivia and Argentina is the result of the war of independence. Between 1810 and 1820 the border changed, until at some point it kind of stabilized where it did. At one point Patriot armies reached as far as the current Peruvian-Bolivian Border, only to be repelled by loyalist armies sent from Peru. At some point the loyalist conquered Salta and Tucuman in Norhern Argentina, only to be sent back. While it is true that *Bolivia was close to loyalist Peru that to the United province strongholds and that armies from lowlands have some difficulties fighting in *Bolivian highlands, I do not think it is necessary for the border to be settled where it did in OTL.

Bolivia was the first place where revelions against Spain took place in 1809. *Bolivia (then occupied by loyalist armies) even sentrepresentatives to the Congress that declared Argentina's independence in 1816. Bolivia was seen as important for those in power in Argentina in the early 1810s due to its silver mines (by then a bit depleteed but still important, specially in the minds of the people), big population and the existance of Charcas University where some of the members of the elite had studied.

It is still hard to know if it would have stayed united with the rest of Argentina in the long run. If it did Argentina would have veen very different.

Pretty much what Admiral Brown (nice name) said. Most of the Upper Peru (save for La Paz) declared its support for the May Revolution and the Buenos Aires Junta, but it was quickly overran by Spanish armies coming from Peru. Argentina was never able to re-occupy the Upper Peru (there were 3 different expeditions to the Upper Peru, all of them ended up failing) until a guy named San Martín took command of the Northern Army, looked at the situation, said "fuck Upper Peru we are never breaking through that", left a local Caudillo in charge of waging guerrilla warfare in Salta to keep the Spanish away, and proceded to cross the Andes and declare the independence of Chile and later Peru proper.
It doesn't help that Sucre, the person who liberated the Upper Peru once and for all, was a commander in Bolivar's army, and that by 1825, when Bolivia was declared independent, Argentina had collapsed into civil war and what was effectively warlordism. This made the idea of joining Argentina again (which was a possibility considered by some) extremely unattractive.
The best way to have Bolivia remain part of Argentina, in my opinion, would be to avert the collapse of the Argentinian State and the Anarchy of the Year XX (which dissolved the Northern Army), and instead, when Sucre is leading his campaign into the region, have the Northern Army join the offensive from the south, meeting the Bolivarian army. Or just have the Spanish be much more incompetent at suppressing the initial recognition of the Buenos Aires Junta in 1811 and 1812.
