[@Sekritter]Depends on the character really. I mean if you have the money for that kind of an upgrade then yeah it would conceivably be possible. Keeping in mind that pinnacle athletes are already particularly fast, I would ask how they have compensated for the potential wear on the human body? Since in this setting humans are MOSTLY the same as we are currently so speeding up the metabolism or causing the body to move at accelerated speeds might be damaging? Food for thought but the short answer is yes
