Toilet drain damage

pf22

I helped pull an old toilet at a relatives condo. I thought it would be a simple replacement but it has a lead drain pipe with a flare that sits over the metal flange. The lead flaring appears to be part of the original lead drain pipe since I couldn't locate a seam or joint. Part of the lead flare broke when lifting the toilet. The rest appears to have corrosion on the surface and the flange is rusted. It's the original toilet, about 35 years old.

A plumber told me I could just cut away the rest of the lead flaring and pipe flush to the floor, remove the old flange and install a device which has a flexible sleeve that expands tight against the old pipe as you screw it together. It also has a molded in flange. (I've seen it) I also noticed a small gap between the existing drain pipe and floor cutout. I planned to seal that with wp silicone caulk.

My concern is the old lead flaring. Does it partially support the rest of the drain pipe? I can rotate the old metal flange with the rest of the lead flare still there over it. It doesn't appear to support it but that's without a toilet sitting on top. I know little about plumbing and being on top of other units the relative is paranoid. Being unemployed they really want to save on a plumber.

Thanks in advance.
