Having seen variants with regular uL or with longer range lasers instead of the SPL, I decided to post my @Remover of Obstacles -inspired take. Can also be considered a non-hero version of >this "Meganova" build by w(a)^8t<. Focus lasers on legs in scouting (where people generally get close anyway).
20 heat sinks on a Nova and no more than two laser types? Automatically a great build! Short range lasers are the best for Novas in scouting. With longer range lasers, you depend on your team the entire time to tank for you so you can keep damage up. With shorter range lasers, you only depend on them to get you to the fight unharmed.
