I made a variant of this influenced by a drink we tried at MAP Maison Dalston, and it was surprisingly excellent:
60ml Tequila Blanco
25ml Lime Juice
~12.5ml Monin Hibiscus Syrup
2 dashes Malvern Chilli Bitters
Shaken with ice and strained into a salt rimmed glass.
Aimed to tone down the sweetness somewhat; the hibiscus still came through, but tempered by the chilli and salt.
