No one is altering the Bible. I’m explaining the meaning of the text here. The authors of the Bible didn’t know what asexual reproduction is and couldn’t possibly have meant that - this is a modernist addition to the text kind of like what Answers in Genesis does. In any case, you admit you don’t really believe the angels perform asexual reproduction:
Obviously I do not think that angels reproduce in the same way as bacteria.
So, what do you really think? That new angels were created by Lucifer:
I think the only reason a third of the angels followed Lucifer is because he created them.
In other words, you don’t actually think angels reproduce at all, sexually or asexually, but that more were created after God made the initial bunch. Since this is what really you think, your earlier insistence that angels do reproduce makes no sense at all.
As for Satan being able to create angels, you might start thinking about forming your own sect around that one.
