PhilDAS never content with the bikes I already own

This is my preferred one -

How much seatpost is in the frame? Enough to cut the bottom off - expoxy it as far down the inside of the seatpost as you can to make a shelf/shoulder for the rest of the post to sit on? cut some additional shims to give you adjustment of a few min increments up from where you want it? The bottom of the shortened seatpost can then sit against the glued in piece of post and secure with the clamp? Add a 2mm shim to make it higher if required etc?

That could work but I'm not sure I'd firstly be able to sand a decent surface that far down in the frame and secondly be able to wrap enough carbon around the bottom section and epoxy so that it's a tight fit whilst also being able to get it through the hole in the top.

I think what I'll probably do is ditch the clamp/wedge which will save a few grams too (bonus) and wrap the very bottom of the post in a layer of carbon to thicken it a little, smother it in epoxy and put it into the frame.
Then with the bike on the turbo or something, try to find the exact ideal height to set it at with me hovering over it while pedalling.
Carefully get off it, leave it a while to set a bit and then wrap the exposed seatpost and the top tube/seat tube junction all in carbon to make one seamless ISP frame.
I can cross the adjustability bridge in the future if it comes to it and chop the post clamp off and figure out some kind of topper down the road
