Weapon on model different to warscroll

[AdamJ]

I've recently completed an Aelf Dragonlord and decided to equip him with a halberd and reaver bow. On his warscroll the melee weapons only mention a lance or blade. This is despite the fact the halberd comes with the kit and the warscroll even has a picture of the Dragonlord with the halberd. Do you think I could get away with using the halberd as a blade in a tournament? I've attached a pic!

Thanks,

Yes. It looks good and appropriate. Why would anyone care?

As per Cavalry Champions with swords instead of lances who have rules for lances.

Yes sure, just make it clear to your opponent that, 'this weapon counts as....'
