any interest in expanding rfc1345.mim?

Hi,

First of all, rfc1345.mim is great. I've been using it for well over a 
decade, and I love how useful it is for quickly changing between 
scripts. That said, every once in a while there's a character that I 
wish it had that it doesn't. Lately, I've been collecting those in 
https://github.com/dseomn/dotfiles/blob/public/.m17n.d/rfc1345-plus.mim. 
Which works great for me, but I figured I should check: Would anybody 
else find those useful if I contributed them upstream?
