Can I physically change the keyboard to azerty?

Hi,

The keyboard I have is not the CM Storm, although similar I've got the Zalman ZM-K900M, mecanical keyboard

It's a native Qwerty keyboard and I'd like it AZERTY.

I swapped the essential keys but remain a few I can't change.

In Qwerty The left $@$* key is bigger than the franch version, and the Enter key is smaller.

Shift key is taking two "slots" instead of one on an azerty version. So I'm not sure if it's doable.
