After the new LRMs I decided to give the PB another try and it makes more sense now using the LRM-slot on this one. Tried it a few matches only but it reliably dished out 600-800 dmg, thats about double of what I often did with the pure brawler fit. You can drop one LRM ammo and/or the MPLas for more leg armour and/or tag. Another option that is perhaps the best one is to downgrade MPLas for MLas and trade on LRM ammo for BAP+leg armor. Also, on this build it may be feasible to use the LPLas range module since its rather cool. Have fun!
