Illegal, and highly so. So I doubt you can get clearance from the RTO etc.

I know you are adamant on the Maruti angle, but I would suggest a Daewoo Matiz, Cielo, or even a Contessa. The single advantage is that all these three have a higher boot area/C pillar than the bonnet/A pillar. This would make a convertible/topless car look better. Also, all three are cheap.
