Door locks, trunk locks, ignition lock cylinders....

I have a few cars here that need door locks. A couple have ignition keys but no door locks. I know that I can buy lock sets but I am wondering if there is another way.
With the variable quality of aftermarket reproduction stuff, I wonder what can be done to "re-key" a lock cylinder.
Can a locksmith take an ignition key and reset the guts of a door lock to match the ignition?
Could they take a used door lock, make a key from it then "re-key" a ignition cylinder to match?
I probably have 15 or more door lock cylinders from the late 60s to mid 70s and they all look the same, even ones for trucks. I also have several 1970+ style steering column lock cylinders with no keys. It would be nice to be able to use them.
Since these came new with a matching door and ignition, how hard could it be?
I have the following that need door locks:
67 Dart
69 Dart (Needs ignition key too)
70 Charger
71 Duster (Needs ignition key too)
72 Duster
75 Power Wagon.
I don't know of any locksmiths near me. I could probably find someone if I looked. I just wondered who else encountered the same situation and what you did.
If you used a reproduction, what brand worked well for you?
