I remember several years ago, I stumbled across an article in a LR magazine on this subject. I read a little into it for curiosity, but didn't pay it much mind, for obvious reasons. If I recall, the dash is cut out the same on both sides. The instrument pod is designed for easy removal and should actually fit where the airbag is, and vise-versa. I believe the major work would be the relocation of wiring and brake master cylinder and new steering box for RHD, and the sorts.
That was before the D2 times though.
But for oddity purposes, I would leave it. You might actually fool some poor soul into thinging they are behind a car with a passenger and no driver going down the highway.
