Just saw this a few of hours ago, and as a tattoo lover (I have three), I just have to participate.
The first time I decided to get a tattoo, I designed a complicated one featuring the Liverpool Liverbird and the five Champions League stars. Thankfully, the artist advised against it, and gave me some guidance. The key, he said, was to have a core theme, keep it bold and simple, and make sure you won't be embarrassed displaying it in public.
As such, after mulling over your list of requirements (Alêya Lovi Thai/21.1.12/heart shape/font continuity), I came up with the below. Hope you like it!

ps: Regardless of your final decision, please consider posting a photo of the tattoo once you've got it done. Luck!
