You can enter any register onto the commandline by using ^R, so just do
this if you want (after pressing a, the contents of the register will
appear on the commandline)

:^Rad

If you prefer, you could issue a command to append a d to the register
and then execute the modified register

:let @a.="d"
:@a

And there are other possibilities too....
