Maybe, but it could also stay as romaji "twintail", Japanese people omit the "s", making it sound unusual in English so it still feels Japanese-ish this way
Existing examples for such naming is AHoge Editor (https://ahoge.heyuri.net/ ), or another similar uploader script that is called "STRANGE UPLOADER" by the Japanese.
If it were to go with this and Japanese letters, the alternative Japanese writings could be liek ツインテールあぷろだ or ついんて～るアップロード, there is room to play with it.

I would be happy with tenma too
