No actually. I do have one with that setup, but i have an external backup of the mobile wallet key either way. This is actually a 1/2 with just the tapsigners right now. So i only need to not lose both tapsigners at the same time, & i did this specifically to have one in the safe at home, and one for traveling.

But i do have my mobile key as my account key, so without that and my password, even stealing my phone and tapsigner makes it highly unlikely they can get my coins.
