Probably, but I've never seen the powers of Unicorn / the Psycho frame explained or brought up in any OP hax mecha discussions so I don't know about them. (still haven't seen beyond ep. 1)
BUT if you want know about some really, REALLY bullshit Gundam OP hax suit, have a look at the Gundam Qan[t] or "Quanta". See it can quantize. It breaks down at the quantum level to either just phase through anything (making it practically invincible as long as it has enough juice to fuel it) and able to TELEPORT BETWEEN GALAXIES (it does this twice, once to go to another planet and then back), and theoretically anywhere. As you can imagine this means it has a frickton of juice to fuel that phase form.
It also fuses with what has to be the most OP enemy in Gundam history, the ELS, which are grey goo nanomachine replicators. Touch them and they'll convert your mass into itself and can shapeshift it into whatever the fuck it wants.
In theory "ELS Quanta" could touch the Earth and convert it into a billion copies of itself. Forget OP or hax, it enters the domain of a God.
If I had to pick the strongest suit in Gundam franchise, it has to be it, even without Moonlight Butterfly tech.
