Chinese Shenyang WS-10A jet engines are already in mass production.
Could the WS-10A engine power the J-10, J-11B, and J-15 aircraft? The answer is "yes" if two conditions are met. Firstly, Chinese production of WS-10A engines must be sufficient to meet the demand (including production of parts for maintenance and replacement engines at the end of the expected lifetime) for all three aircraft.
Secondly, I don't know if WS-10A engines are interchangeable with AL-31F engines. If they are not readily interchangeable without modifying the fuselage then the current fighters with AL-31F engines will most likely stay with AL-31F replacement engines.

To conclude the discussion on the use of domestic WS-10A engines on the J-10, J-11B, and J-15, there is a new photograph of a J-11BS equipped with WS-10A engines.

WS-10A engine for J-10B Vigorous Dragon fighter in mass production
Shenyang WS-10A engine (with gearbox at the bottom) is designed to power the J-10B Vigorous Dragon fighter. This version of the WS-10A turbofan engine is said to have 13.2 ton maximum thrust. There are several wrapped engines near the floor.

J-10A and J-10B Vigorous Dragon evolution
The top photo is a J-10A with AL-31F engine. The second and third photos show a J-10B with DSI intake and AL-31F engine. The fourth photo is a J-10B with China's domestic WS-10A engine.
This sequence of pictures illustrates the evolution of the J-10 family from a J-10A (with AL-31F engine) into a J-10B with advanced DSI technology and WS-10A engine.
In the sequence of photographs, it is easy to distinguish between the AL-31F and WS-10A engines. The "flexible petals" on the WS-10A are a lot shorter than on the AL-31F.
