I couldn't tell you about the clip, but you can unscrew the thumbstuds and switch them to the other side. It will take some armstrength and some replacement loctite.
I don't know what Buck's opinion on doing custom work is. If they aren't into it, I bet if you emailed them, you could get Strider Knives to drill and tap the clip holes in the g10.
I dunno what to say about the linerlock. Those would still be orientated for the righties. Bummer.
