Hey there GermanSumo, you sure know how to target a weak spot man. All jokes aside there may well be a viable product model to the idea, but the difficulty is that space battles of that nature run completely counter to the 'tentpole' element of BattleTech. Best way to say this is that BattleTech/MechWarrior is all about Mechs, Wars & Warriors. Space battles tend to neutralize all three of those to a level beyond the grasp of the players. Is there are place for such games - oh absolutely, but it's a niche within a niche and would ultimately prove a counterproductive business model.
Now with that said I would love to see it done right and well. It would be really cool! But it would have to be it's own game and thus far we've not seen a compelling pitch/model for it. Never say never though... if HALO Fleet Battles can exist, anything is possible. :0)
