Will AR Rahman take the Yuvan way?

Malayalam director Shajoon Kariyal is all set to begin his next venture. The film is about five friends and a two-hour incident they come across. Biju Menon, Lal, Suresh Krishna, P Sukumar and Sunil Babu play the five friends and Biju, who is also the co-producer of the film plays a percussionist from AR Rahman’s band.
So, the makers are planning to bring AR Rahman on board, not to compose music, but to do a cameo in the film. They are also hoping the ace composer would give his nod for this.
Yuvan Shankar Raja recently did a cameo in the Ajith starrer Billa 2. Will Rahman take the same route?
