Guile supports extra/foreign types just fine (so-called SMOBs), which is
what strings and buffers are in Guile-Emacs so far, and if I understood
Robin right then the intention is to keep them so for a while, probably
even in the first "release" of Guile-Emacs.

SMOB types don't cause any extra memory usage or data access time AFAIK
so that probably works fine, the only problem being that Scheme and
Elisp strings are two different data types.  You get all of the other
benefits on the meanwhile which don't involve the mixing of Scheme and
Elisp code.
