I was thinking about some screen tool, like Vaphit includes now in its sets. One side for removal and one for getting the screen back in. Maybe with a dome shape, to get the screen the perfect curve to fit and not stress the weakpoints of screen to much.

Here's a simple, inexpensive DIY screen setter that I used to set my DV screens, then upgraded when buying my first Dani V2. This works for half or full bowl screen settings. Here's how: Simply buy a 1 inch / 2.5 mm in length bolt with two matching nuts with the diameter that is a little smaller than the inside diameter of the Dani's / DV's bowl. Take your bowl to the hardware store to get the best fit.
After cleaning the machining oil from the metal, thread both nuts on to the bolt. The nut closest to the bolt head is for locking purposes only, so just thread it out of the way for now. The last nut threaded on is the important one as that will be the depth adjuster for your screen.
With the bolt head placed on a flat hard surface, place a 'flat' screen on the inside rim of the bowl and slowly and evenly press the screen down in to the bowl. If you chose the right size diameter bolt, the screen should remain perpendicular to the bowl's sides as you press down on the bolt. Inspect your progress as you proceed and when you see the screen is close to the proper depth, thread the nut down to meet the rim of the bowl, and then back it off 1/8 or so turn.
Repeat the above instructions until the screen is placed to your satisfaction. Now that you have achieved the perfect depth for setting a screen, thread the other nut down to meet the depth stop nut to lock it in place. Be aware that it's possible to accidentally move your depth setting nut when snugging the two nuts together. Hand tightening is all that is necessary.
It can be a pain in the ass to set the tool up the first time, but after that for each cleaning it will only take a few seconds to replace the screen perfectly.
