I've made some progress towards my goal: gphoto2 (hints from here) works if you use the function "Remote control (EOS Utility)", rather than "Connect to smartphone".
I can list and download photos. The speed is 1.9MB/s in optimal conditions, so roughly 14 seconds to transfer a raw+jpg. This is far below the supported 802.11n standard (similar speed reportedhere), so that's a very limiting factor.
Functional, but not yet great.
