Velo Orange also has a narrow 27" rim.

I can't say if it is any better than the narrow Rigida or Wolber or similar rims from yester-year.
It looks like it is only offered in 36h.
There also appears to be a Sun CR18 in both 32h and 36h.

But, as others have mentioned, the selection of rims is very limited.
The selection of tires, especially narrower sizes are also very limited. I think I found a 27x1 Panaracer.
There is also a wider 27x1 1/4 Gatorskin.
In theory, your contact patch would be slightly better for 27", but I have no idea how much overall difference that would make. Probably minimal considering that one is missing out on all the high-end tires. Vittoria Corsa Speed? Various tubeless? Tubulars? Open Tubulars, etc.
