Is Kunal-Siddhi marriage why Mona got Richa's role

Mona with her funny nose would make a good vamp.
Maybe the first Richa, Madhurima couldn't pout and change colors like Ekta's Vamp brigade does...

What say guys?

1. Pehla breakup, Richa ne baal katwadiya and she now has a short hairstyle.
2. Now Kunal will wed siddhi; will she go bald?
