To what degree would glasnost or perestroika be in the works? Is it possible they would have similar effects on weakening the union of soviet republics as OTL?
You can read about some of his ideas on his wikipedia page. It seems he wanted gradual change from "state-administered economy" to having the state simply guide enterprises. There were some failures and stuff, and there was political backlash, but the era where those plans were implemented also saw high growth in production, grain exports, the salary for Soviet citizens more than doubled, and the standard of life improved. If he was in a greater position of power he could prevent this from reversing like it did in Brezhnev's reign. Gorbachev's attempt failed because it was too sudden, and too late.
A good idea for a Soviet survival would be, say... Khrushchev's Virgin Lands Campaign does not fail. It failed OTL largely due to them not taking proper measures to protect the soil and stuff like that. If they are smarter in that regard, they probably would not be so adverse to future reforms as well, but Khrushchev did not seem to plan any and this scenario demands Kosygin, so let's say that thanks to his increasingly erratic behavior he is still ousted as per OTL.
The troika initially consists of Koysgin as the Premier, Brezhnev as General Secretary, and Anastas Mikoyan as Chairman of the Presidium. Theoretically they are equal, but Brezhnev had been assuming more power as the leader of the CPSU. However, (another POD) Brezhnev suffers a bout of extreme illness and is forced to retire from office entirely as his condition soon deteriorates badly. Kosygin, to fill the vacuum, takes his place and to avoid being seen as a total dictator by the government relinquishes his former post of Chairman of the Council of Ministers to Andrei Gromyko, who until now was the Minister of Foreign Affairs.
Ostensibly Gromyko presides over the ministry and decides domestic policies, but Kosygin decides Party policy and holds more clout, and also Gromyko and Mikoyan are quite loyal to him as well. He uses this opportunity to implement his economic reforms, which although not totally successful, increase the standard of living in the USSR dramatically.
How is this so far? Not too sure where to go after this, though. I don't have a clue as to Soviet politics, and haven't the faintest idea what the Soviet foreign policy TTL would be like. Thoughts?
