You could reduce the size by building a non-multiarch version of R
(e.g. only 32 bit). That will approx half the size of R and then you
only need a single tool chain.

Using mingw-builds [1] you could create a minimal version of the tool
chain, e.g. by not building gdb, gfortran, or other stuff you don't
want to support. I would not recommend hacking the installer of the
current rtools.
