As Eagler said, I hope not - with the run-in needed for torps combined with the acks laser accuracy against non-evading targets, I would really hate to make it to drop only to have a "thud" instead of "boom" from the torpedo.
Having a difference between national torpedoes would be neat, eg, IJN planes were the only ones that could carry Long Lance torpedoes.
I'll support that SM-79 (pretty neat looking, then I do think its the 3rd engine that really makes it cool) if the Beaufighter Mk X gets support votes in return

Cheers
