I think you might run into some issues with the two charge pumps heterodyning. Also depending on the amp circuit you are using, a charge pump may not output enough current

That data sheet says the caps can be “inexpensive non-polarized 1uf” which would probably be a multilayer ceramic

The diodes are usually chosen for a low voltage drop, you see 1N5817 in the main page charge pumps
