New Cert Idea

[Bashere]

If this has already been thought of before...oh well.
Anyway here is my idea for a new cert type.
Weapons Training-for 4 cert points you would be able to purchase 1 empire specific weapon used by another empire from terminals, provided you already had the cert for that weapon type. And if you wanted to change it you could, just like dropping certs, you would only be able to drop 1 every 24 hours.

Opinions?
