Emma with A twist

I have been wondering if J.Austen's "Emma" will still be held a very good one if things turned out this way in the story:

Mr. Elton,in my twisted story, did not marry another woman despite Emma's first rejection--- a rejection she made not because she did not like him but rather because she is not ready for a serious reationship. He will turn out to be the third person that will hinder the blossoming relationship between Mr. Knightley and Emma. In this part, Mr. Elton will be the cause of Mr. Knightley's jelousy. To make things harder for Mr. Knightley, Emma's father did not favor the paring of Emma and Mr. Knightley due to age difference--- it is like an over-my dead-body stand point...

This is not a good ending right? So I'll leave the " what happens next to the readers" ^_^
