Those crossover points and slopes look OK. I might cross the compression driver a bit higher though. The BMD450 isn't very good below 1.6kHz, and you will want to put the biggest horn on it you can get. If you cross it in at 1kHz on a horn that's too small, you will get bad distortion problems (a harsh sound in the upper mids). 

Really, a 1.4 or 2" driver on a large 800Hz horn is a better match for the MT12 horn. The MT12 only has 60 degree dispersion up to about 800Hz, thereafter it narrows.

Also remember that the BMD450 response isn't even as flat as it looks on P Audio's graph, so you will want to use a PEQ to cut quite a lot at about 3kHz, in order to not have your hi-mids overwhelm the rest of the range. In fact this applies to most compression drivers. A lot of new users don't do this, and wonder why their rig sounds harsh....
