Install the pipewire-jack package, this will give you a drop-in replacement for Jack. You can use qjackctl or some other Jack patchbay program to set up the connections as usual.
Also, you probably need to set up a group for realtime priorities, infinite ulimit, etc., as you do with native Jack. Some distributions have a package for that. (E.g., Arch has the realtime-privileges package. You then just add your user to the realtime group and you should be set.) Finally, you probably need to set up a decent buffer size for Jack. (The default in Pipewire seems to be 1024 which is way too high on most systems.) qjackctl lets you pick a buffer size in its Setup dialog. There's also an environment variable (PIPEWIRE_LATENCY) which can be set at login, and various other settings in the pipewire config files. Also, there's a force-quantum setting which can be modified using pw-metadata; see, e.g., https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Guide-JACK#set-buffersize . We've been running this kind of setup in our computer music lab for quite a while now. It's been a little rough in the beginning, but since Pipewire 1.0 everything seems to work fine. And the ability to simply route PW/Pulseaudio devices into Jack and vice versa, without the need for any special bridge software, is a great bonus.
