Maybe you can, but the probability of failure is high. I remember
talking to someone from the IT staff of a venerable auction house;
they tried a "big bang" solution, i.e., do new software from scratch
instead of tinkering with the old one. Eventually they had to abandon
the project after huge costs were incurred; and the reason for
abandoning it was performance problems that could not be overcome by
throwing more hardware at it.

I.e., the software is really messy. How can you be "gloriously
successful" in such a setting (except maybe in the sense of "Paths to
Glory")? My impression is that you cannot do substantial changes to
such software, so either you live with it being hardly modifyable, or,
when the pain from that gets big enough to overcome the insistence on
bug-for-bug compatibility, eventually you replace it with something
written from scratch, probably with a specification coming out of
requirements engineering rather than from the old software; of course
with a high probablility of failure.
