Poor women often addicted to alcohol selling their bodies cheaply and/or vagabonding in Whitechapel or the City<<
Mrs Nichols might be classed as addicted to alcohol.
If the stories about Mrs Chapman's "ginny" liver are true is might have been an acohiolic.
Mrs Stride wasn't an alcoholic.
Kathrine Eddowes enjoyed a drink, but I've never heard her described as addicted.
Ditto Mary Kelly.
The the vast majority of Victorian East Enders led some kind of transient life style, "vagabonding" is a very vague definition to isolate the victims by.

Execution in places with a high risk of fast discovery<<
I'm not sure how you are defining "fast" in this context, but otherwise, I agree.
Honour based mutilations and posing<<
I don't believe Mrs Nichols could be described as posed or, by your definition, "honour based mutilated".
Mrs Chapman didn't have facial mutilations
Mrs Stride was not mutilated in any way and it is highly debatable that she was posed.

Women, extremely poor, living in doss houses and one room accommodation, in need of money.
Swift blitz attacks, in the early morning hours in locales which were risky, and at weeks end and public holidays.
Overpowered, smothered, throat slashed in all. There was posing except in the case of Liz Stride. I don't know what you mean by 'honour-based mutilations'. The killer certainly mutilated the abdomens of his victims except in Stride's case, and there were facial mutilations in his last two victims but we don't know his motivations for so doing.
My 2 cents:
Easy targets, i.e. any woman who offered herself to him when he was looking for a victim.
Blitz attacks that rendered his victims senseless or unconscious, cutting the throat in such a way that he wouldn’t get much blood on him and getting them on their backs to facilitate the abdominal mutilations.
Mutilation of female parts of the body with a knife.
All the best,
