Pyro Siliconable?

Now I know that the Ghost and USA edition Pyros are siliconable and I’m wondering why the original Pyro isn’t siliconable?

The original Pyro used Dif-pads. And I think it also used THIN dif-pads which would make it harder to silicone.

The groove is not deep enough

I’m not gonna get pads anytime soon and I’m impatient so I silied it and it seems to be working fine so far
