No, not really. It can't synchronize back with another consciousness. If two users sat in tandem, it could do both but the experience would be like a trainer-armor with two sets of control systems: One master and one slave with Slave being the trainer and Master taking charge if Trainer goofs up (just like how they teach flight).
It's a combat system, and Nekovalkyrja are more likely to have combat experience than any other race, since they're only used in the Yamataian military. Since Nekovalkyrja already have computer-type brains, would there even be a demand for this system?
Not really, since they lack the life-experience to use it properly.
Their capacity for judgement is much younger and much slower compared to true life-forms because it's been rapidly cultivated.
In short: A Yamataian using this will surpass a typical Neko and come close to the rates of advanced AI (think X1 Ghost from Macross Plus or the YF21 on Limiter Release if it operates at the highest levels) -- However, a Neko with age akin to most life-forms (18 years +) will see improvement, just like a Yamataian would.
As for computer-type brains, a Neko might have these capabilities -- But I have never
ever seen them demonstrate it. The general consensus or bias is that Neko are some how 'disadvantaged' emotionally, just like Bladerunner's Replicants - And the system relies quite heavily on that emotional response: That ability to get in the zone which you can't do after 6 months of boot-camp.
You need life-experiences to form your motivations and to calm you and keep you paced and relaxed so you perform at your very best.
People who get excited or enjoy the fight or fear it miss things. They make mistakes. They make the wrong decision. They try to hurry the fight to get their "reward" (as stated in the Mindy: Neko getting a "high" from beating an enemy).
This is more like a Zen approach, giving a pilot of sufficient memory and experience a temporary glimpse at what would be like combat enlightenment.
edit:
I'm beginning to see a trend in my submissions: They place performance above sustainability.
