Lede for zsun wifi card reader?

im new here and have just recently bought one of these zsun wifi card readers.

I installed an openwrt image provided by a polish group. All works well. But what I really would like to have, is the latest lede build on this device, but unfortunately I do not know how to achieve this.

Is anyone working on such a device? Is there somewhere a documentation explaining the necessary steps to do this?

This is their git tree, from a quick glance you'd need to port the last four patches. OpenWrt trunk & LEDE now use e.g. /etc/board.d/ for LED and network settings, so you might need to adjust a few bits and bolts.
