Hey everyone, I'd like feedback on a cocktail I'm trying to create based on Earl Grey tea.

I've read somewhere that during the interwar, earl grey tea was associated with women's alcoholism because the middle class women would use it as a mixer. This inspired me to create a cocktail that combines an aesthetic of an middle class bourgeois alcoholic Englishwoman with our contemporary concept of cocktails.Take note that this is just a raw draft in my head, and the cocktail is in its first steps towards completion.Since this is the first time I am trying to invent a cocktail from scratch, I'm not quite sure how to start.I know for sure that it will be served in an manhattan pre-chilled glass. But let me tell you the ingredients first and explain my reasoning behind each one.Earl grey infused london dry Gin. This is pretty straightforward. I want to give earl grey a protagonist role in this cocktail, so what's better than infusing it directly with the base spirit. I thought about brewing strong, high-potent earl grey and adding one part of that but I disliked the idea after all. However I am willing to give this a try too.french distilled blueberry drink (boisson fermentée, 9% alcohol by volume). I like the idea of a myrtle tone be present along with the earl grey. I've drank earl grey tea paired with this distilled blueberry product and it gave a soft honey-like flavor that will sweeten the cocktail just enough without using any other sweeteners. Myrtle gives out a smell of exquisite female perfume that will compliment the bourgeois nature of the cocktail. The product I currently have is of high quality as it comes straight from Alsace. The french myrtle will compliment the french earl grey brand I intend to use. However I am worried that all of this France in my cocktail will eliminate the English part of it. I consider getting an English brand of quality earl grey, so if anyone is aware of a nice brand please tell me.Grapefruit juice. Earl grey tea is basically black tea with the addition of citrus oils (I think bergamot orange). It is a very pleasing tea to drink and it definitely has a strong citrusy flavor. I picked grapefruit juice for its citrus status as well as its bitterness. Also I am a furious fan of grapefruit and gin. So I think that grapefruit will be a worthy choice as it will both enrich the earl grey'ed gin and provide the desired bitterness.Angostura bitters. This is my secret weapon. It will provide the spicy bitterness. I want this cocktail to be all about interwar alcoholism that affected women, I want the taste to be kicking, I want the taste to be all about complex bitterness. I want this cocktail to breathe the idea to the drinker of a woman, a woman in her 30s, just after the Victorian era and first world war, a woman expressed by the then raging feminism, a bourgeois woman that drinks her problems away. Nothing better than some bitter action then.Myrtle leaf, dried or fresh, and Grapefruit peel after expressing the oils as a garnish. The blueberry leaf is a overstretch but if I happen to find (or maybe plant some seeds) it will greatly improve the cocktail. Aesthetically mostly. The grapefruit peel will enhance the juice and citrus.This is the draft in my head for now. I haven't worked on the ratios at all. Also I'm not sure whether this should be stirred or shaken, leaning towards the former. I am also thinking of adding another ingredient but mostly I want to keep it simple. I'd love some feedback and ideas. Thanks!
