XL Hot End to go >400C
I've been researching options to get me to advanced material capability, and hopefully be able to print PEEK or close to it.
There is options from E3D Revo High‑Temp (HT‑X)

Even with a 450 °C hotend, PEEK needs:
Chamber: 90–160 °C
Bed: 120–160 °C
Ambient stability: no drafts, no cooling fans
I have the enclosure kit for the XL, but it looks like its a stretch.
RE: XL Hot End to go >400C
Im not sure if it is feasible. Let say you make it fit... then you'll have to fork a firmware and do the necessary changes, change your heatbed, provide cooling for the controllers, build a proper enclosure, attach a chamber heater and reprint everything in pccf. There is still the issue if the electronics on the toolhead can cope with the both the heat of the nozzle and the heated chamber. I dont believe Prusa will bother with this since it will probably be an expensive kit and will mean a lot of testing to the upgrade path. Also XL hasn't had any improvement kit imagine making an overhaul kit.
RE:
I’ve been working on giving my Prusa XL these capabilities for over a year now.
In the meantime, I’ve started by learning on a smaller model. I learned a lot from my Prusa Core One HT, which allowed me to apply that knowledge to this modification on the Prusa XL.
The bottom line is that several modifications and changes are necessary if you want to achieve the goal I mentioned.

I like the core 1 approach. Messing up my XL down an unknown path is not something I'm comfie with. I have an older 3S but may just leave that be too, and just invest in a standalone unit like the core one.
