Guosheng Zhuang of 3Uaudio Microphones actually makes his 34mm K47 with 6 micron membranes.
He does sell transformers separately, but I haven't seen him offering capsules without a microphone.
Guosheng Zhuang offers three type of capsules, k67, k47, k12. Each one in two options "dark" and "bright".
Single sided for 100$.
Double sided for 150$.
Direct purchase via email.

I bought 3 of these capsules from WGT over a year ago when they were on AliExpress for about $52/each delivered. Overall I thought they were kinda too bright and lacking the low end I was hoping to get out of them. They did have a similar "honk" that I heard when trying out a MP mic with their K47 (and their schoeps circuit mod) but I didn't get a chance to try them side by side to really compare. But to be fair, I'm not really sure a K47 style sound is good on my voice. I also thought they were a touch too mid-forward for my purposes.
The upside was that, not too long ago, I pulled them from the modded mics I had them in and sold them on Ebay for $50 each and they sold fast.. like within 24 hours after posting them fast, so if you buy and try and don't really dig them, you can most likely offload them and recoup most of your out of pocket cost.
The capsules I purchased were cardioid only. I almost wonder if their dual membrane capsules sound better.
Nope, at least for my taste, single sided sound little bit better.
It's exactly same sounding as MP version.
In most typical topologies of chinese microphones, like raped U87/emitter follower and schoeps, they sucks.
These capsules are pretty great in both, tubes and FET circuits, but there's always minimum of good optimalisation of the circuit for it.
I will repeat myself here:
You can run it up to 70V, rather symetrical cylindrical headbasket (non U87 style), no capacitor between capsule and fet
Also it's important to get optimal polarisation voltage. It's strongly dependent with the circuit type.
