The RD coalition is suffering from many shortcomings in terms of capabilities compared to other more well rounded/built coalitions. The lack of a truly high-end ASF is one of them. One way to make the coalition more "meta" or rather bring it up on par with many others is to give the Su-27 used by China the F&F R-77.
There are bascially 3 things people needs to consider befor screaming "no" or "not possible on the SK variant".
1) ingame story
2) IRL events
3) most importantly gameplay
For ingame story telling it is basically "everything goes", since NK got the T-90, why shouldn't Soviet hand out some of their surplus R-77 which is also given to East Germany front nation. Especially the second Korean war campaign unfolds in 1991 and the realigment of USSR to its Asian neighbours.
For IRL events i will repeat the reasoning from fine-tuning thread: China was the first one allowed to buy an ASF which is considered top-tier in Soviet Union. It invested alot of money into Sukhoi and the development of the R-77, since the SU after breakup was in serious economic trouble and willing to part from its top tech for cash. Accoring to few Chinese sources half of the initial run of 200 missiles went to China, that would be around 1995.

(obvious shorter version) so far R-77 just began small scale production. Russia only produced around, the first 100 is used in various tests and the rest of 100 is prepared to be sold to China
Consider the SD-10 (proto of PL-12) was seen in 2001 and the delivery of Su-30MKK with its weapon package (includes a number of R-77) is around 2002. It is reasonable to assume that China got hold of the missile much earlier.
The issue is which aircraft fires it. In this case there are 2 candidates:
The J-8-IIM from 1995 with the Russian Zhuk radar and thus capable of firing the R-77. Being a export plane it is activly marketed as a cheap F&F mid range AAM slinger.

The other candidate being the second batch of Su-27SK delivered to China in 1995-1996. It is stated to being a improved version upon Chinese request. The capability of firing the R-77 is one of them, and that version is called Su-27SMK. There is another offer made by Russia in 2003 called Su-27SKM to upgrade Chinese Su-27, but rejected cause J-11B was progressing at the time.

(obvious shorter version) Added the capability to fire R-77
To be fair this is one of two narrative of how the R-77 and the capability to fire it got to China. The second and more visible one being the Su-30MKK deal with its weapon package.
Personally i think the possibility of a Su-27SMK with the improvments requested in 1995 is not far fetched. Consider the SD-10 got pushed into service in 2001 the expertise and insight on such advanced AAM needs to come from somewhere.
I would again ask Russian forum members how they see this. Any informations you guys can share?
Finally the ingame balance for RD ASF looks like this: J-8C, MiG-29, Su-27SK. J-8 and the MiG (needs its authentic MRAAM loadout) are already mid-tier options, it would be more productive to make Su-27 another high-end RedFor ASF, especially when considering the IRL events/development and ingame storytelling as the reasoning for authenticity.
If this is a no go, rerole J-8C to J-8IIM is still a possibility and it will basically trade place with Su-27SK in terms of gameplay.
