Looks cool Peter!

There will be some tools coming for MoI v2 that should help doing that kind of a thing without it actually being a full blown component system.

For example the new on-surface snapping should help move things along a surface. Also I will be adding in some orientation type stuff as well. The on-surface snap will be part of the first v2 beta, probably the orientation tools will be in a further release though.

I would think those along with booleans should enable you to get this kind of stuff working pretty easily.
