Well that's hard to say. If you were to compress all that bone mass into a typical rack of say a 10 point rack, it would be huge. Since the 205" is the measurement of the antler growth plus the spread and we, for arguments sake we assumed the spread was the same and we aren't reducing the amount of antler growth, it would probably still be around 200". If you take a 10# weight and cut it up into 100 pieces, the total sum of the pieces will still be 10#. Again, the number of points doesn't matter in scoring, only the amount of antler growth, plus the spread determines the score.
I think you are thinking that if you removed all of the non-typical points and growth it would be a typical rake smaller in size and that would be correct but that requires removing antler growth from the rack. If you removed enough antler, you could make it a simple spike buck. But that buck grew 205" of bone. If you took that 205" of bone and reconfigured it into a 10 rack, it would be huge.
Let me put it another way. Lets say you had 10# of clay and made an exact replica of the 205" non-typical rack, then took that 10# of clay and made a typical rack but had to use the whole 10# of clay, how big would that rack be? You're not removing any clay, you're reshaping it into a different shape.
I've got friends in West Virginia that tell me "if you were to roll WV flat, it would be bigger than Texas.
