I would be against removing/replacing the acu laser with something weaker and cheaper (but ok with it being split into two upgrades provided it costs the same to get the laser as before cumulatively).
Currently it gives a high risk option for surprise defence and offence with and without cloaking - eg if your opponent has no omni yet and cant maintain spy plane coverage you can surprise them with a cloaked com. It takes slightly longer to get a cloaked ACU than a monkeylord, but offers greater potential upside as you take 0 damage if they don't realise until too late what you've got. For the non-cloaked version if you manage to get it early enough you can also try and get a surprise ACU kill by disabling your attack to hide that you have the laser, baiting their com within range, and then killing it, or going for a risky transport drop.
Overall I'd see it already as better than the billy, in that the billy offers an expensive upgrade that can in some situations do quite a bit of damage (unshielded with minimal tmd), but is easy to counter, and your com is relatively safe. The cybran laser upgrade is far more devastating where it works, but your com is much more likely to die when it doesn't (and even when it does if you're using it for offence instead of defence)
