Clearly the words “British Empire” would have to go. A humbler perspective would need to apply.
May I suggest OBG – Order of Bens and Glens. MBG, CBG, KBG (No Russian connections) and DBG would complete the set.
KG could become Knight of the Galluses and OB could become OB(F) – Order of the Bath (Fortnightly).
CH would easily translate to CHH – Companion of the Happy Hour and the Order of the Thistle and Order of St Patrick could be combined to become the Order of Patrick Thistle.
