Why do you want to change them? The low-dropout parts are only an
advantage if the input supply voltage is low. With the stock power
transformer, that will only happen if your AC line voltage is under 100
volts.

If you *do* have low AC line voltage for some reason, a much easier way
is to replace the convention rectifier diodes with Schottky diodes. They
have half the voltage drop, and so raise the unregulated DC supply
voltage by about 1 volt.
