Uploading modified Blizzard core files?

I couldn’t find this info anywhere, sorry if I missed it. For all know this is done all the time, but I haven’t been involved in SC2 editing in ages. If I unpacked starcoop.sc2mod and repacked it without the forced inclusion of Stetmann/Mengsk data (to fix the actor and unit duplications), can I upload it? Or is that not ok?

Maybe as an extension mod or an arcade map?
