Can a drive sprocket be modified?

[wisewood]

Calling all chainsaw gurus, I have a small home owner class Mountfield saw (Mc382) that I would really like to fit out for detail carving.

I could just get a quarter nose bar and use the existing sprocket (3/8)but I'd really like to put a small dime bar on but would need a 1/4 sprocket. There doesn't seem to be a specific lo pro rim and sprocket for this make so as the title says is it possible to make one fit?

Here's the parts list if that helps

 

Cheers,

Si
