We already have that, I think:

    locate-file-internal is a built-in function in `C source code'.
    (locate-file-internal FILENAME PATH &optional SUFFIXES PREDICATE)

    Search for FILENAME through PATH.
    If SUFFIXES is non-nil, it should be a list of suffixes to append to
    file name when searching.
    If non-nil, PREDICATE is used instead of `file-readable-p'.
    PREDICATE can also be an integer to pass to the access(2) function,
    in which case file-name-handlers are ignored.

Isn't this what you wanted?
