A lean burn gas engine should only need the same tweaks that they made to diesels. Triple catalyst and DGI are what many manufacturers are working towards, if they aren't already there.

Can't sell those here anymore either, they run afoul of the same strict NOx emissions limits that doom most diesel engines.

The 1992 Honda Civic VX was rated for 49 MPG, but it weighed about 900 lbs less then the current one. Lots of people said they got over 50 MPG and one hyper-miler got 70 MPG averaging 3 fill ups.
Looking at the US lineup of Honda, you wouldn't know they made diesel engines. I wonder if they will start selling them here when the new fleet mileage rules get closer to the implementation date.
