I plan to get the railings repaired by having a metal shop weld
extensions onto the legs. What's a "proper" or better way to reattach
them to the steps?

What Jim said except ... can't tell but what shape is the rest of the
leg in and how heavy were they to start with? Looks like lots of paint
bubbling which is good sign of corrosion on insides and given the
obvious length of time (based on stains) they've been rusting away, it's
quite possible there's hardly enough material left to make them worth
saving. That's a call can't tell from those photo's; you'll probably
get a good input from the shop guys. Which, btw, find a shop that does
such stuff routinely not just a general purpose weld shop; you'll likely
do far better.
