Sure.  All you need to do is build RF sections for each of those frequency 
ranges, create detectors for SSB, AM, TV FM audio and WFM audio as used on 
the FM band and modify the PLL frequency synthesizer that forms the first 
local oscillator.
  
If you don't know what that means, you are in way over your head.  If you do 
know what that means you will realize that it is a tremendously difficult job 
that requires an experienced RF technician to accomplish.  It would also 
result in a scanner the size of the old "general coverage" shortwave 
receivers from the '50s.  
  
Frankly, it would be much less expensive to buy a scanner/receiver that is 
built to cover all of those ranges.
