Is your question one of translation, ie how to write 'come what may' in Hebrew?
That would be בוא מה שמאי
If you want to find a good 'font', then lexilogos.com has some simple but pretty ones
WARNING:
(1) Proud though you are of your faith, you would be well advised to think very carefully before displaying Hebrew on your body. Some (muslims, in particular) will hate you for it, and assume you to be a zionist zealot. How would you feel about your tattoo when the Muslim terrorists choose YOU to be the first hostage to die?
(2) Some Jews will despise you for it (the orthodox, in particular)
