The only way I would use this design style (removing parts) would be if the stripped down models start at T1 and get built up logically into either HQ style or support style

Not a big fan of this one. It feels weird that a feature in the T1 factory gets removed in the support factories.

Based on Blodir's feedback. What about swapping the support factories you have there for T1 and support T2 while using the old t1 as support t3? I like the look of these ones but as Blodir pointed out the smaller frame should translate to build power.
