The actor, who made his Bollywood debut with the horror-drama "1920", was the winner of "Khatron Ke Khiladi" season five.
"I am open to doing dance-based reality shows. I would love to do something on those lines as I like competing, it would be very interesting," Rajniesh told PTI.
The actor said he was set to feature in celebrity dance show "Jhalak Dikhla Jaa", but that clashed with his upcoming film "Direct Ishq".
The "Ek Paheli Leela" actor, however, does not see himself participating in a show like "Bigg Boss".

"No, I cannot do that. I don't think I will be able to take part in something like 'Bigg Boss'... That's a different ball game altogether."
"I am in talks with a production house for a mini series. I am very open to doing a limited series because you do it like a film. Work for three months or six, then come out of it and do other things. But I cannot do the long, never ending shows at this point of my career as it will be very difficult for me," he said.
