maybe it can work take the basic concept from OOT, which would be the lava moat, and the bridge but instead of just making the original ganons tower make it as if it would be in twilight. it may work maybe something like hyrule castle from N64 but with the view of peach's castle where you can see almost the entire castle.the only concern would be the actually design of the caslte with hyrule castle and peach's castle we had both stages being fair (besides it own interruptions) and both stage for the most part flat. if the basic concept is not applied then ganons tower would end up the current hyrule castle, which is still not a bad thing but i do agree with darkurai it is really hard to imagine
