Did it in VM within W8.1 with first few builds but find it too restrictive. As you mentioned syncing, visually speaking and some settings are from one of my before 10240 builds. I don't remember exactly when but I stopped syncing before that.
I don't get that MS policy of restricting only interface changes in non-activated insider builds. If that's so people wouldn't use insider versions as a free windows, that will not stop most of them because they wouldn't care what it looks like as long as it's free.
