Yes.
A good reference point that should be seriously looked at is the cups
implementation. They basically have the same problem : hot-plug devices,
a small set of common drivers but lots of setting mixes (defined in
windows files or in the cups case in ppd files).

(I'd go even as far as to say than a really good implementation of an
"hardware settings db" should be shared by cups, xorg-x11 and probably
others).

Now where cups fail miserably is :
1. remembering manual settings (either it scratches them or creates a
new auto device alongside the old manual one)
2. localization. In the printer case that means A4 vs letter. Dunno if
there are the same problems in X11, except possibly in the keyboard
space.
3. convincing all the apps that were built for static settings to adapt
to the new dynamic world. (moz & firefox for example store a printer
info copy in their conf file, as they do for screen dpi info. Updating
dynamically this file is only a bandaid)
