Did we buy the wrong sink?

Did we buy the wrong sink?

We redid our laundry, and we installed this cool sink that we bought cheap at Habitat for Humanity:

http://www.americanstandard-us.com/assets/documents/amstd/spec/SpecSheet_1474.pdf

But now we find that it has a 3" diameter drain hole, and every drain assembly we can find is 3.5".

We could get one of these:

...but the problem is that we need to connect the drain to the wall, not the floor. Because:

a) That's where the plumbing is, and b) We need to store stuff under the sink

What are our options? Is it possible to find a 3" diameter drain basket assembly? Is it possible to bore out the hole to 3.5" without destroying the sink? (It's cast iron with a fine porcelain coating, so it seems unlikely/very difficult). Do we just need to find another sink?

Thanks in advance for any help!

It looks like that trap/strainer assembly does drain to the wall. The bit on the floor appears to be a sort of foot for mechanical support, not part of the actual plumbing.

That aside, this looks like it might get you where you need to go.

The same vendor also offers this one, which includes an adapter that takes the outlet down to 1.5".
