I know stainless steel is corrosion resistant but from experience even SS corrodes when exposed to high temperature+ highly corrosive condensates from wood burning or rain water getting in the chimney somehow!Insulated SS liner, bricks/mortar to cover exposed tile at top of existing hack job, a cap that seal inside . No water or condensation. Get a cleanout proper at the bottom of chimney with a cast door, and a SS T- to connect the liner through a thimble to the stove in the room.
I'd add a damper after the stove pipe, not required but good if you get a fire.
Best performing SS is the high Chromium and Nickel (austenitic type non-magnetic even when "tried" with strong neodymium magnets!
Only way to avoid corrosion is to prevent condensation forming if possible!(50mm of insulation or more). If not, just use temperature resistant brick and rebuild the damn thing when needed
That's what we do around here in Romania when using ceramic tile wood stoves! Stainless steel insulated chimneys are used only in wood burning central heating units,wich are "kind of" expensive at 9000-10000 euros just the stove! But it's the only choice if the house to be heated is located up in mountains ,remote(but peacefull place). And it has a lot of space hundreds of square meters on a few stories...
Plus only wood as fuel ,since gas is nowhere near, LPG tank is not an option,again too up in mountains...
These high Kwh stoves also can burn all kinds of coal, for extended burning time,so it's even easier to load a competent 4x4/6x6 20 ton truck with coal or wood and get it up there in the dry,summer of course! Maintenance too done in spring/summer time ,to be ready for the next winter!
