Anyone done this, is it feasible?

I realise it's not desirable, but it may be necessary

Yep no probs.

Most budget exhausts are done this way. Mine has a mild steel flange with stainless tube welded up with mild wire.

it can be done, what type of welder are you using? arc will be the strongest and you can get a special type of rod that will do it but i cant remember what they are called.

Best thing to do before welding 2 different types of material is to heat both before welding, when i have welded to cast turbo housings i have put both parts in the over for half an hour.

Do you use stainless filler or mild?

A lot depends on what you mean by stainless steel.

Stainless isn't one type of steel it is hundreds with very different compositions. -- some low grade stainless irons (the stuff kitchen sinks are made from) you can do a satisfactory low strength weld to mild steel but with true stainless steels you will get a very brittle weld if they do form weld at all.

I do in mine and have no problems!

I've been using stainless repair patches for years doing up old cars. Apart from a few more sparks there's zero difference or problems in using it. No need to change anything.
