Wasted Space by Vibration Motor

Hi everyone! I've found a little problem, we need to solve: The vibration motor wastes a lot of potential space inside the phone (1-2mm). This Image shows that:

We need to check for the following to solve it:

• Is there another place we can put it?
• Can we move it there?
• If not, are there alternatives to this vibration motor?
• Do they have a lower profile?
• Is this change worth the effort?

Possible space

A possible place with enough space could be the rim above and below the screen. But there are other very important parts such as the ports.

Let me know your thoughts!
