Is this a good idea to make the following text message encryption:

 - accept text from the user 1
 - store the text into a document in the form of some handwritten font
 - convert the document into an image
 - apply noise to the image
 - encrypt the image somehow (hide the fact it is image)
 - send the image to the user 2
 - show the image to the user 2 as image

**EDIT.** My purposes:  
1. Avoid existing widely used smartphone messaging apps, which could be which can be monitored by law enforcement agencies.
2. Make a simple own secure messaging application to just text exchange **p2p**
3. Be sure (as far as possible) that our messages will not be **automatically** intercepted **by standard means** used by law enforcement agencies. *I don't know that standard means, and also can never know for sure*
4. Provide greater resistance to interception than existing widely used smartphone messaging apps **at the expense of some inconvenience**
