I'm okay with this idea. Sounds reasonable for a nifty roleplay supporting feature. Though I would suggest a few things:

Hit/Crit - What you basically said for hit is fine. I also wouldn't mind SL1's dodge, and injury messages back in place of Hit rating and Dodge. Crit, however, I feel should be just be displayed as normal. Reason being is it's too -broad- of a concept from an IC perspective. On one hand, you could view it as the chance to hit an enemies weak point. On the other hand, it could be just a point where your character just is able to really lay their weapon into the opponent just in general. There's a variety of ways it could be interpreted, so unless you could fine a definitive way to describe and vaguely display it to the player, keep it the same. Damage itself? I wouldn't mind if that was removed from the initial targetting either.

Movement Range - Yes. Yes. 100% Yes. People normally wouldn't be able to tell initially off how quickly someone could get across the battlefield.

Level - I don't know why this isn't already hidden with the rest of the stats. I suggest it be replaced with some sort of "threat" level, like the dungeons have. "Puny-looking" for like Lvl 1-10 and 'Horrifically Imposing' for like 50-60. idk.

Sestuna - That, in particualy, I'm a bit uneasy about. The sword is magical, so there's no real way for you to gauge whether or not it's abilities are "beyond" the realm of reality.

Modifiers
Mechanation Traits: Mechs should have some sort of trait that allow them to see normally unseen statistics, maybe not all of them, but some of them at the very least.
General Traits: Traits to analyze an opponents range of movement after moving, their known skills, and other various things could also be introduced perhaps.
Hidden Statistics PvP Toggle - If none of the above are added, what Rendar suggests would be nice.
GM Powers - Should be able to circumvent all of these above mentioned features for the sake of stopping bug abusers. If bugs -do- arise.


EDIT:Armor Rating? Well, that I feel is also beyond just mere normal comprehension. Sure, a person can appear to be wearing no armor at all, but in reality they could be a lot more sturdy than they look, especially in a fantasy setting. The Defense stat dictates this.
