I’d stick with replacing it w/the proper part if at all possible. I had to do that w/my truck one time, pretty simple diy’er fix. Ignition switch configurations are make/model/year specific. Have you checked at Rock Auto? They may have it mail order. Or at a Kia dealership? I don’t understand the $200 price for a used one. Do you have one of those “pick and pull” places there in your area? If so, you can find out if they have a wrecked version of your vehicle there using the pick & pull web site. And the parts prices are often listed there too. I don’t see pick and pull charging $200 for that part, more like $25-$35.
An auto electric specialist could probably wire you in a custom ignition switch, but that’s not something a diy’er would usually do unless they were an experienced electronics hobbyist or electrical engineer etc. Suggest not to attempt this on your own unless you have the needed expertise b/c a mistake could damage something very expensive.
