Hypothetical gravel setup for touring Europe this summer

Okay so this summer I am planning on going on a two week journey across europe, seeing some awesome nature on the bike and also visiting a friend somewhere along the route.

Picture 1 is thought proces/picture 2 without my drawing/picture 3 is the bike I bought for gravel

Anyway for this I bought a (aluminium)gravel bike so I got a sturdier frame then my current road bike. I used the road bike for bikepacking before but it is not fully equipped for alot of bagage.

I am trying to use as much as my old gear as possible on the new bike, and adding some DIY gear to the bike to make it more functional. Right now I am still making the plans before buying anything so I would love all thoughts on the setup idea so I can improve more.

I am trying to ditch my backpack I used now carrying gas burner+stove+espresso machine and a 3L camel bag. I would like to store the camel bag into a additional made frame bag as well as my food. And the gas burner + stove and espresso maker would fit perfectly on the fork on some DIY strapped on bidon holder with electrical tape. Additionally I would use a bigger dry bag strapped on my steering so not only my tent but also additional gear like sleeping pad and tent floor fit there and maybe some clothes. And for the rear in blue I would make a DIY stabilizer from some spare steel I will bend/weld to make the saddle bag mor stable as it is a bit unstable on the road already and for gravel it would not be better I guess.

If it will not fit all my stuff I will resort to a double pannier bag, but that will cost like 150-200 euro for a good one(not buying a cheap one I need to trow away). But I want to prevent buying that 🙂

So any suggestions or tips are welcome, as much critique please 😉
