The bottom bracket is not your biggest problem. As long as you have the needed tools, swapping out the bottom bracket and cranks is about a 15 minute job. Rather, you will have a much bigger problem with your rear wheel.The 11 speed 105 cassette will not fit on your freehub. 11 speed cassettes require a freehub body that is just under 2mm wider than the one you currently have because the 11 speed cassette is thicker than your current cassette. So unless you can upgrade your rear wheel with an 11 speed cassette body, you cannot upgrade your bike to 11 speed
