When I first read HGTTG in 5th-6th grade, it was exactly this kind of language that drew me to it. It enhanced the humor for me, and it would feel dead to regionalize it, and lose an integral part of the character.

My thoughts exactly. The Britishisms add extra color and absurdity while simultaneously bringing the characters more to life. Besides, archaic and excessively formal language is almost a hallmark of British humor as I interpret it.
