It can, but has to be offset by higher capacitor bank voltage and the resulting increased current and magnetic fields crushing the plasmoid. At this point LPP’s nailing down the parameters which are relatively easy to repeat from shot to shot. Later on, these settings can speed up scientific confirmation in other labs.
Achieving reliable 3MA currents may be a short to mid-term set of engineering challenges.
