what was wrong with this question?

To the OP: the width is irrelevant, your shoes will be wider than the pedals, and you'll have more underside clearance than with clip in pedals.

i agree with the others that 105 pedals work just as well as the DA,s at a fraction of the price, but there is no harm in swapping pedals as long as you grease the threads and are careful not to crossthread.
