Here is my Phags-Pa Tibetan Script version for writing English. The letters are idenitcal in appearance to the actual Phags-Pa Tibetan Script, however they do not connect as the original does. I hope you enjoy.
GS Unicode is a project I'm working on so (almost) all languages get support! With 14,564 non-spacing characters, this font is finished (as of Unicode 13.0). Please tell me if some of the characters aren't working. I'll try to fix them as best as I can!
