Lord of the Rings: War in the North [.paq files]

Hi everyone!
So Lord of the Rings: War in the North uses .paq files, for which bacter on another forum wrote a neat QuickBMS extract script.

Code:

# Lord of the Rings: War in the North [.paq files]
# QuickBMS script - created by The Bacter
# work-in-progress version!
IDString "pc\x00\x00"
get UNK_40000000 long
if UNK_40000000 != 0x40000000
  print "Error! Exiting. Current value: %UNK_40000000|h% Expected: 0x40000000"
  cleanexit
endif
get DATASIZE long
get UNK_00000004 long
if UNK_00000004 != 4
  print "Error! Exiting. Current value: %UNK_00000004|h% Expected: 0x4"
  cleanexit
endif
get DATASTART long
getdstring DUMMY 112
get NR_OF_FILES long
set TTSIZE long DATASTART
math TTSIZE -= 128
log MEMORY_FILE 128 TTSIZE
for i = 0 < NR_OF_FILES
  get FN_pos long
  get FN_len long
  get DIR_pos long
  get DIR_len long
  get DUMMY long
  get DUMMY long
  get File_REL_START long
  get File_Size long
  set THE_POS long DATASTART
  math THE_POS += File_REL_START
  goto  FN_pos MEMORY_FILE
  getdstring FN FN_len  MEMORY_FILE
  goto  DIR_pos MEMORY_FILE
  getdstring DIR DIR_len  MEMORY_FILE
  set FULLPATH string DIR
  string FULLPATH += "\"
  string FULLPATH += FN
  string FULLPATH += "."
  string FULLPATH += i
  log FULLPATH THE_POS File_Size
next i

It can unpack the archive, but the files within have some strange extensions (every file has a different extension consisting of numbers) and can't be directly edited (well, hex edit is a bit of a burden). I'm mainly interested in the texts of the game, since I'm trying to translate it to my native language.
Can anyone shed some light on these, if they can be edited and/or repacked?

Thank you in advance.
