For multiline problems, you need a looper, a script that has an N, a $ test and a branch t or b, so you can pile up lines in the buffer. Duplicates would need to be sorted to be adjacent, and 'sort -u' or 'uniq' if already sorted, will get them, simpler. You do not have associative arrays like bash, awk, perl in sed to record all and detect dups in an unsorted file.
Don't think of it as one sed command, but one sed instance running a script.
5 and 6 are just this script line: s/[)(]/\\&/g
I find it is better to put looper functionality in a separate sed instance on the pipe. Sometimes, for speed, I chain many sed in a row, so each holds the line the least time.

strip
STRIP(1) BSD General Commands Manual STRIP(1)
NAME
strip -- discard information from ELF objects
SYNOPSIS
strip [-d | -g | -S | --strip-debug] [-h | --help] [--only-keep-debug] [-o outputfile | --output-file=outputfile] [-p | --preserve-dates]
[-s | --strip-all] [--strip-unneeded] [-w | --wildcard] [-x | --discard-all] [-I format | --input-target=format]
[-K symbol | --keep-symbol=symbol] [-N symbol | --strip-symbol=symbol] [-O format | --output-target=format]
[-R sectionname | --remove-section=sectionname] [-V | --version] [-X | --discard-locals] file ...
DESCRIPTION
The strip utility is used to discard information from ELF objects.
The strip utility supports the following options:
-d | -g | -S | --strip-debug
Remove debugging symbols only.
-h | --help
Print a help message and exit.
--only-keep-debug
Remove all content except that which would be used for debugging.
-o outputfile | --output-file=outputfile
Write the stripped object to file outputfile. The default behaviour is to modify objects in place.
-p | --preserve-dates
Preserve the object's access and modification times.
-s | --strip-all
Remove all symbols.
--strip-unneeded
Remove all symbols not needed for further relocation processing.
-w | --wildcard
Use shell-style patterns to name symbols. The following meta-characters are recognized in patterns:
! If this is the first character of the pattern, invert the sense of the pattern match.
* Matches any string of characters in a symbol name.
? Matches zero or one character in a symbol name.
[ Mark the start of a character class.
Remove the special meaning of the next character in the pattern.
] Mark the end of a character class.
-x | --discard-all
Discard all non-global symbols.
-I format | --input-target=format
These options are accepted, but are ignored.
-K symbol | --keep-symbol=symbol
Keep the symbol symbol even if it would otherwise be stripped. This option may be specified multiple times.
-N symbol | --strip-symbol=symbol
Remove the symbol symbol even if it would otherwise have been kept. This option may be specified multiple times.
-O format | --output-target=format
Set the output file format to format. For the full list of supported formats, please see the documentation for function
elftc_bfd_find_target(3).
-R sectionname | --remove-section=sectionname
Remove the section named by the argument sectionname. This option may be specified multiple times.
-V | --version
Print a version identifier and exit.
-X | --discard-locals
Remove compiler-generated local symbols.
DIAGNOSTICS
The strip utility exits 0 on success, and >0 if an error occurs.
