There's no way to import reader syntax using the `r6rs' reader.

The creation of mutable lists by '(...) isn't actually a reader issue;
it's the work of `quote' as exported by `rnrs'.

I'm puzzled, though, that you're trying to use R6RS library syntax but
you seem willing to use many PLT-specific features. Why not just write
in `#lang scheme' syntax instead of `#!r6rs'?
