You only need 5 to 10 psi to bleed using the pressure bleeder.  As you have suggested, the plastic brake fluid reservoir and the gravity-feed hose(s) joining it to the M/C will NOT take much more pressure than that when newer, let alone when older and more fragile.

  I would definitely NOT recommend 20 to 25 psi, as someone said earlier.

  Hmmm, not sure whether the line from the remote reservoir and the master
  cylinder can withstand pressure, or what kind of cap it uses.  I haven't
  owned a Bay in years, so my memory's hazy.
