I think the most viable solution for the Peraltada would be to Hockenheim-er-ise it.
No, I don’t mean castrating it.
When Tilke re-profiled Hockenheim, he added a chicane of sorts in between the hairpin and the entry to the stadium section. And while the entry is quite slow, the drivers can accelerate on the exit. A corner like this could be replicated behind the pits to cut the entry speed to the Peraltada, but not dramatically slow. The drivers would still take the corner at speed, but they wouldn’t be going at full throttle. The trick is to slow them down just enough to make the corner safe, but not so much that the challenge is gone. Something like this is what I have in mind:

I also changed the very sourthern end of the circuit to cut out a corner and increase the entry speed to Turn 9.
The other alternative is this, which is a little more extensive in its changes, but it still handles the Peraltada with the same logic – that the entry speed can be controlled with a medium-speed extension of the existing Esses just as easily and effectively as it can be with a brutal chicane:

And in the most extreme version, the chances for an accident at Peraltada are further reduced by lengthening the circuit, thereby decreasing the overall number of laps:
