Maybe if the bonuses(speed, science pack drain) were better than the biolab(2,50%) it might be worth making. But the same bonus for a much more complex machine to make, it's more trouble than its worth. You could try speed=5, drain=30%. Fusion is late game mechanics too, which makes it even worse to get.
Maybe a fission lab would be a better alternative to mid game lab alternative? Or add both fission and fusion labs? New mod name: Nuclear Labs? Fission lab speed=5, drain=30%. Fusion lab speed=10, drain=20%.
