There are locks with short backsets, but Kwikset doesn't make them. If your door has such a narrow stile that you cannot put a household duty lock into it, you are probably not interested in security, so anything you can find will do the job. Look online for locks for French windows or patio doors.
If you are interested in security, then check out Adams Rite locks, which are used in narrow stile aluminum storefront doors, but they also make some for wood doors.
If you are replacing a very old lock and your style is big enough for a 2-3/8" backset lock, then do it right and treat it like a new installation. Use a jig that can hold the hole saw in the right place, use a router to cut away trim that will get in the way of the lock, and install a modern lockset.
