What do you think?

In a word

NO

Is the right answer.

This.

Sorry but Amy had her chance and the public did not vote her in

Nope. Amy has had two chances to go through already. I don't like the idea of voting someone in. I think it's unfair they get a by to like weeks into the competition.

They are disadvantaged because they don't have the 4 weeks of growing fanbases that the others have had though.

Amelia Lily was able to top the votes and sail to the final.

Not really, didn't Amelia top the votes at one point? Fanbases can be remarkably persuaded or won over.

I still think it's unfair; I mean whose to say she or any other act would have lasted this long if they'd gotten through on the judges choice or wildcard. It is pretty much giving them a free pass a quarter of the way through and to the stage where they could potentially get a slot on a nationwide tour.

They dont need to have a replacement, they just dont have a 'double eveiction' in the coming weeks.
