Mangled frame- what would you do? (140-150mm fravel bike content…)

As with the mega, a Titus El Guapo will take a 150mm RS RVL with a fat external lower cup headset. The On-one mixer taper something is fat enough
If you think it might be too steep it looks like Works components are doing similarly fat lower cup angle adjust headsets that would fit?
With a 70mm stem, I dont think it feels too steep tbh, it doesnt feel too slack or anything, but not overly steep. With the slightly longer c/stays and the fork would down its a pretty stable climber
