Hard to answer "can I damage", what I can say is that I ran a GTA02 A5
like that for a while and the boost regulator for host did not get hot
or appear to change its behaviour afterwards.

The regulators generally operate by watching their output and adjusting
what they are doing according to what they see -- if it starts drooping
because we are pulling a lot of power, they start working harder.  In
this case the theory is they see that there is nothing to do because
nice 5V level they wanted is pouring over them anyway, so there is no
real conflict.
