Coat of arms and item type changing enhancers

[Thunderbird]

Can the coat of arms allow you to carry an extra big item.

Also can you curse somebody with lose your headgear while they have the "Funny Shaped" item enhancer on headgear or foot gear and it is designated as headgear without them being able to change what the item type is before the curse takes effect or all curses immediate?

Thanks,
Thunderbird
