[flame suit on] ...and with appologies to Ham...
To my eye, and this is strictly a personal opinion, the traditional PC looks martial and dated, sharp yes, but dated. How about getting a tailed tux and having a tailor trim off the tail ... kinda bring the look away from 19th/20th century military formal, and into the less decorated 21st century civilian formal; then you have the added advatage of being able to use it and kilt for the Masonic events as well (if that's permited).

Do I recall correctly that you're involved with SASS? Some time ago I saw a "western tux" jacket (i don't recall where) that had bobbed tails, kinda like a PC but different. That sort of thing might have multi-use potential for you.

I couldn't find that coat, but I did find this at Renton Western Wear:
