Of course it is possible. To Leshan, you can take bus from Chengdu Xinnanmen Bus Station to LS Xiaoba Bus Station. After arrival, transfer a taxi to reach the Buddha.

To Emeishan, you can directly take a bus from Xiaoba Bus Station. You will be taken to Baoguosi Bus Station, which is the closest one to Mt. Emei. This bus station has direct buses to Chengdu.
