Choice of シティ and 市 in translating "Mega city police"


I'm trying to get a stylized translation without too complex kanji for "Mega
city police".

The kanji for police for example is too complicated for what I need so I was
trying to get the Katakana translation but I did this online and I'm not sure
how right or wrong it is.

  1. メガシティポリス (this is the one I would like to use)
  2. メガ 市 ポリス (Unless a version with a kanji in between will make it better)

Which option is better and why? Can you help me decide or tell me a better
way? Thanks in advance :)

Edit: Not sure why I got downvoted :( a comment telling me what I'm doing
wrong will be helpful. Didn't I came to the right place to ask this maybe?




「メガシティポリス」 would be a valid and natural-looking transliteration. (Please note
that this is not called "translation".) It just flows on the native level.

「メガ 市{し} ポリス」 would make **no sense** to us native speakers (if you are trying
to appeal to native speakers, too.) This would be possible only if the city's
name were actually 「メガ」.

A natural-sounding and non-katakana term would be 「巨大都市警察{きょだいとしけいさつ}」, but
you obviously would not go for it.
