Possible? I wouldn't say no. However, there are lots of things that
should be put into consideration. The first one that comes to my mind
is namespace and directory structure. I do not think that putting
1.6.1 in a different namespace and directory is a good idea. That
would hurt backward compatibility. v1.6 code should work as before.

I'm sure there are other issues as well. However, I won't close my
mind on the idea. If boost only had a *smart* configuration based
download such that when your compiler is VC6, a copy of Spirit 1.6
is sent instead, it would be ideal.

I'd like to hear what Hartmut, Dan, Martin, etc. think about this

1.8 is fully backward compatible with 1.6 code. You need not do any
re-coding at all, unless you used some undocumented features.
