[Spaceships] Using two smaller ships to simulate a larger ones

That's exactly what I did in my GURPS Spaceships Design Spreadsheet to create intermediate SM systems. Most systems scale at either a 1/3/10 or 2/3/5/7/10/15/20 pattern, making intermediate SM's pretty easy: 1/2/3/6/10 for the former and 2/2.5/3/4/5/6/7/8.5/10/12.5/15/17.5/20. For weapon damage I just used a value half-way between the two, so for the dDam2 listing where it goes 2d/3d/4d/6d/8d I used 2d/2d+2/3d/3d+2/4d/5d/6d/7d/8d.

I think that the biggest advantage of using the extrapolation method is that all ship designs still look the same - they all have exactly 20 systems.
