Can we form co-operative housing society in pagdi system ?

Hi,

I am from Thane, Mumbai, India 

I live in a 4 story building, which is 40 years old...

Total there are 55 tenents, all are paying rent regularly, and getting rent receipt of the same..

Three land lords....

A   B   And C

A sold to B in 1995

B sold to c in 2000

now C is land lord...

However,, neither in property card nor in 7/12 the names of B & C..

When B and C Called for meeting with tenets.. nobody could show us the registered documents ?

on property card and 7/12  A's name is still there..

My question is, can we tenents form Co-oprative Housing Society         ( not Welfare Society ) and enter in the procedure of deemed conveyance... ?
