Bad design?

Is this a bad design:
I have 5 connections (switches on a X10 mini home controller) that either
need to get shorted with pin A or pin B.
I am planning on using two CD4066 bilateral switches
(http://www.fairchildsemi.com/ds/CD/CD4066BC.pdf).
Each of the 5 inputs would have TWO connections connected to it, one from
pin A and one from pin B (outputs of two of the 'spare' switches). As long
as I am careful not to have both switch A and switch B enabled at the same
time is this a bad design?
I know that I could use an inverter to protect against having both A and B
active at the same time, but I am going to use a PIC to control the
switching. In an effort to keep parts to a minimum I can do this with
careful coding.
Thanks
