My man, glad someone gets it 
Basically you just buy a new nose cone depending on whatever is trending that year
YUP! DO IT!!
4 years ago I drafted this picture. Essentially putting an Axis tray board, thin dockstart board, into a skirt of a larger board. In my case I was going to build a downwind board.
The tray board could be hot-swapped into multiple skirt designs; downwind, wing, parawing (didn’t exist then), prone, boogie (blah!!!).
The board I built was out of XPS foam, because it was waterproof, and didn’t therefore need any significant lamination. Light in the ends, just foam with enough fiber, 1.4 oz glass, to keep from flecking away.
The board ended up 7’ 10” x 21”, 9.75 lbs @ 128 liters. It was 7.6 lbs / 100 liters and to date no one in the world has posted anything lighter (lbs / liter). Similar concept but not modular. Strong under the feet and robust box reinforcement. Built 3+ years ago and no hollow board, no production board, no custom board (that anyone has shared) has been lighter. Crappy XPS and my first build. I thought it might last 30 sessions.
I used the board, The Sailfish, a month ago and it was still working 190 sessions later. Boxes installed with the carbon arrow method above.
Granted it had gained weight, from the addition of material where it had signs of wear. But its still alive. I think its @ 10.75 lbs now.

Beasho - I remember some of this discussion back in the good old days of that other forum. I’ve also followed pretty closely some of your board builds. Just to be clear - did you ever try building something like this with the “cassette + hull” concept?
I’ve also thought for a long time this build method could be very promising. And even for the hollow board builds, I’m not a huge fan of what’s shown on the KT videos with all the bulkheads to stiffen up (obviously it works really well, so they’re doing something right!). I think the super stiff tray/cassette standing area with stiff/strong linkage to the foil box(es) with very lightweight hull structure would yield the best performance
My 4’10” prone is solid Divinycell with internal reinforcement and 2x carbon all around. Definitely heavier but the stiffness and power transfer are insane! I think for prone shapes weight is almost irrelevant - it being so compact and seeing what people do on bigger DW shapes that are heavier with the weight more spread out.
i would say make the central stiff section out of solid D cell and the rest of it Maybe even like an un-glassed fused EPS product. I played atound with the idea some but at the end of the day I’m 90% prone and don’t care enough about bigger boards to Invest the time and energy into it.
I was thinking the stiff section would be like a trapezoid shape , baseplate size on the bottom and stance sized on top and make it geometric for easy CNC cutting. Don’t make it go to the rails cause they don’t need to be stiff and it would allow the stiff section to slot into more different boards.

Yeah this is what I was thinking. I keep wondering what an optimal internal structure would look like, I think some crystalline thing. Maybe additive manufacturing gets there and you can 3D print an HD foam board with optimised internal structure like this crew with their fancy titanium crystal structures which I guess you could possibly get an elcheapo version of
Also interesting to see the guts of an Armstrong and Amos
Oh baby, I love seeing the guts of boards! Can somebody please cut open a portal… For science!
