The last three are already being attacked on separate fronts, a compromise would be hard to make. My state just eliminated its estate tax and Republicans have been clamoring to attack it at the federal level as well.
It's weird how much the Republican side of politics is against the estate tax, given the high level of 'founding fathers desire!' rhetoric coming from that side. The estate tax was put in place for a philosophical reason, not a revenue-raising one, so it is part of the mosaic of the 'ff desires'...
