My apologies if I'm missing the obvious, but why not leave
bibtex-biblatex-entry-alist customizable and introduce an internal
variable, say bibtex-biblatex-entry-alist-builtin and move the current
content into that one?  Then define a function like this:

(defun bibtex-biblatex-entry-alist ()
  (append bibtex-biblatex-entry-alist
          bibtex-biblatex-entry-alist-builtin))

where user entries overrule the builtin ones.  This is what AUCTeX
mostly does for the "big" variables.

Best, Arash
