is this an absurd request?

Hi,
Is there a way to perform the following operations on many books? And if not, Is it complicated to create one?

- Change all the fonts in all selected books to a single font, such as Georgia.
- Convert all .png images to .jpg in all selected books.
- Compress all .jpg images in all selected books by a certain percentage.
----------------------------------------
- To compact comments (and save space):
- Select the books you want to edit
- Right-click
- Edit Metadata --> Edit Metadata in bulk
- Regular expression
- Search field:
