you could spray a coat of paint onto a cast one and whilst still wet stick it to the flat plate you are going to use as the flange and the paint left on the plate is your template!

you will be alrite with a mild steel 13mm thick 1 piece flange , use mild steel for the flange as its better for expanding than stainless and yes you can weld stainless to mild steel
heres some ive done in the past
