I can't imagine the usefulness of switching from regex to literal mode
when the search string contains a complex regexp.

But then perhaps search-ring-yank-pointer and regexp-search-ring-yank-pointer
need similar indirection, or code could be smart enough to detect such
indirection and compute the right pointer depending on where such variables
point to.
