Reducing documents isn't going to be enough:  most of the problem is in 

You should investigate whether the libs you need are provided by other 
packages, or (if you wrote them yourself), whether it's really true that 
you can't shrink them.

You could consider splitting your package into two packages, if there 
are several libs.

You could try to explain to CRAN why you need to use all that space. 
There are packages on CRAN that exceed the 5Mb limit.

Finally, you could choose to distribute your package in some other way 
besides CRAN.
