They already are: druntime/src/rt/cast_.d I wouldn't change that,
I'm more thinking about changing rt/typeinfo/*.d from being
hand-written to auto generated by a template and moving the
object size and layout from the compiler (see verifyStructSize in
dmd) to the druntime code too.
No phobos here, that would definitely be a bad idea.

Right now, if you try to use D without druntime, it will complain
about missing typeinfos and force you to create the classes with
a particular size. Much of it can be auto generated by templates
now (which gives a lot of cool flexibility btw), but you are
still locked into the compiler's fairly strict layout. I want to
open up some flexibility.
