• May I/you/all beings be safe.
• May I/you/all beings be peaceful.

What's most important is to use phrases that are meaningful to you - and not too complex; simple is better.

But do notice how much easier it is to say the original pharses to someone you have great difficuly with - for example your least favorite politician or a terriorist. It might be quite difficult to wish that very difficult people be happy, healthy & safe (maybe you can do the peaceful phrase). But you certainly can wish that those very difficult people be free of troubles of mind - afterall, then they would not be so difficult. And maybe their difficulty stems in part of from troubles of body, so maybe you can do that part as well. And certainly you can wish they be free of emnity and hurtfulness. And when you understand that the only happiness that can be protected is that which is generated via wise and wholesome actions, you can even wish difficult people have happiness that can be protected.
