The entire 68300 series of microprocessors are available for this purpose.
The closest to the HC11 would probably be 68331. None of the software is compatible
between the two, so....

There is the 68HC16 series, which is source code compatible to the HC11, while also
providing 16 bit capability and a Multiply-and-accumulate feature.

So you have two choices, go with HC16 if you have a lot  invested in HC11 software,
or go with 683XX and rewrite everything. Note: this assumes you wrote everyhting in
assembler. If you wrote it in "C", you'll probably have an easier time porting to
either architecture.
