No, I think that Shimano has a unique BCD. 95 mm IIRC. I have similar problem with an SR Custom 3 crank; looks nice, and could in theory take a smaller chain ring, but they didn't make many sizes and the BCD is unique to this crank.

There are people who machine custom chain rings. Not cheaply, though.
