You are going to need > 1MB of RAM, can any 51 based MCU's really
have that much?
Yes, there are 51 varients that have large avalable address spaces. Many of
the c compilers support bank switching as well. I know one company I
interviewed with that was running about 4MB with a bank switched 51.
Even then you might hit troubles with tool chain, you need a fully
featured c compiler (preferably gcc), not the "reduced" functionality
ones common on these little CPU's.
True, this will be the hard part. I don't know of anything that comes
close to a full function GCC like compiler for the 51. I have to do work
arounds almost any time I want to use the standard libarry with it.

But hey, never say impossible. "Very difficult" might be close
to the mark though.
