FYI, the problem of your overlay being rejected by the kernel when applied at runtime should be fixed by the latest patch to the dtoverlay command. The problem was caused by a phandle property being deleted (by the "i2c3" parameter, in your case) without the associated "fixup" also being deleted. See https://github.com/raspberrypi/utils/pull/122.
