German post-war motorcycle tune on 30 HP?

Hello, I’m currently looking for a new screwdriver project for me. Visually speaking, German post-war motorcycles are my absolute favourites, so everything that goes in the direction of BMW r25, DKW rt 250 and Simson AWO 425. I would like to do some longer trips with these motorcycles, especially in the mountains, and can also keep up with my friends with modern motorcycles, for which the performance of mostly under 15 hp simply not ausreic My absolute dream would be a motorcycle with this look/look, but with about 20hp – 30hp and a top speed of about 130 km/h. Does anyone have an idea if, and if so, how to realize it? So the whole thing is realistically feasible, and if so, which bike would be the most suitable basis for it, and which tuning measures, or which new engine could I install? On the internet I have already found this project here, which I am very interested in a Simson AWO with compressor: https://www.youtube.com/watch?v=u-SO_OYI-Pc But maybe someone has other approaches or ideas.
