Basement Shower on Kitchen Drain?

I'd like to call a plumber to put a shower in the basement. Can you connect a shower to the kitchen drain or am I better off using something like sani-flo?

The 2" kitchen drain runs straight down into the basement floor in the area I would like to add the shower.

 

So it's not too complex of a job? So the kitchen drain is used for both venting and the drain? Does the slab need to be broken or can the shower be elevated and the wye is above slab?
