Maybe this is a stupid question, my apologies.

Would it be possible in any DIY way to convert to full internal cables on a frame that isn't specifically made for it? If so, how?

Running the cables through the bar and stem is pretty straightforward. How about the rest of the route?

BTW, I'm talking Di2/disc. So bends are not the problem either.

Drill holes, insert cables?

With this style of stem you can pull brake line through the fork without drilling it if there are no restrictions inside.

For the rear brake and di2 line (or wireless with 12s di2) potentially you could make centering ring and head set cover that accommodates brake line that goes around the steerer tube and then out between the fork and headset. (most probably there will not be enough space tho). Otherwise you have to drill the steerer tube or frame.
So if you have to ask do not do it.

Yes, but ACR requires 1.5 head tube I think, most of the frames are smaller at the upper part...so no go for all bikes and drilling the steerer tube is craziness:)

Well he would only use acr type stem to pull the front brake line trough the very top of the stem.

I did this with my frame. It looks alright, it looks like the first iterations of internal cable, where you can see cables and hoses in specific parts. I drilled a hole in the top of the crown race transition. I then epoxied a liner around the hole. This feeds the di2 wire and hose through the fork into the frame. I use a tharsis stem feeding the hoses and di2 through the top portion. My di2 junction box is in the top of the steerer tube. I pull the box out when I recharge the battery which is in the downtube. I 3d printed a top cover which covers the hoses and wires. The tharsis stem has a collar on the bottom which allows the headset to be torqued down. I used a coefficient wave handlebar which has a hole in the back of the bar to feed hose into stem.

You could use a Deda Box stem.

It has a covet for cables under the stem and spacers with room for hoses in front of steerer.

Of course your fork has to have a hole in order fort the front disc brake hose to run inside.

The forementiond Deda st also comes with recessed race for 1.5" top of headset and you should have, or find one for 1 1/8" top headset.

Also there's a Chanel on YT called Haytabike...

Look at his videos , especially one for British racing SL7...In the nice green color and you'll get the idea.

Which is pointless if your frame isn't designed to have cables run through the upper headset.

The question was how to hide cables in a frame that isn't designed for it, not how to do it in one that is.

And there he ends if his fork is not ready for internal cable routing....maybe if he finds some d-shaped fork from Ridley or Colnago and it fits his frame...

I belive bmc also uses the same style of steerer tube. But if he decides to go this way he'll have a problem of difference in colour of the frame and fork. So now we came to a point where it's cheaper to sell existing frame and buy one that suits his requirements.
