I don't think so, at least in the way you're intending. But a lot of other things that were once thought to been impossible have now been done thanks to some rather creative ability makers, so that might not mean much.

Well. my idea was to have it be slow- and encourage people to NOT camp in the uninabitable areas. It's for a set of maps my friends and I use. And if a fleet sits in the middle of randomly moving debris long enough, yeah- it'll be beat up! that's kidna the point

Maybe make it 50 damage with a 45 second cooldown, that way a healthy scout has a chance of getting through, as long as it doesn't dally, and a Colony frig will at the very least get to capture an extractor and maybe escape the GW.

If I had Sins on this comp, I have an idea, but I have absolutely NO idea how to explain what's in my head.

Maybe if you post the whole current code for the planet you want to change?  At the very least, someone with expierience modding could come up with something.

Well, if you do figure it out, please tell us.  I'll keep thinking about it, but I'm not a modder (Yet)

You have given me an interesting idea for planet based defenses, tho.  I wanna use Flak Burst, but not use antimatter and have it constantly fire into roughly 1/3 of the GW at any enemy object in range every 10 seconds or so, but at 10 dmg per hit, before mitigation, dealing anti...whatver armor LRF has.  (Light, I think)

You could check out the Distant Stars mod. It puts new effects on all the planets. Only one does damage though, and that's the one for white dwarf stars, I think. It could help.
