They're both 8-bit microcontrollers with a roughly similar set of
peripheral functions (timer, ACD, serial port, etc). But the similarity
ends there. The programming model for the H8 is compltely different from
the 68xx series.

I don't know of anything like that.
I think the HB development tool of choice is Interactive C, which compiles
to its own intermediate bytecodes. These bytecodes are much more flexible
than the RCX ones - the HB interpreter implements a general purpose stack
machine.
Actually, I'd be more interested in the reverse of your question...has
anyone ported the HB runtime to the RCX so we can use Interactive C on the
RCX?
