My personal opinion as far as the computer game goes...if Yang can figure out a way to make it work, then its good enough for me.
Besides, the way the game is set up, even if you do 'convert' a mech to DHS, the base heat sinking doesn't change, so its not following the rules there either...you can put all DHS on a mech and still only get the base engine heat sinking, instead of that being doubled like it should.
If I am playing table top, then by all means TT rules will apply. However, for the computer game...well it has its own rule set.
