Yes, but that's not the problem. The problem is these Agilex devices are insane overkill for that task, and you likely won't be able to buy the SKUs in a reasonable form factor or price for that use case. The Mister worked so well because the actual design of the device has the right blend of peripherals/compute and Intel/terASIC ate the NRE to design and manufacture it, and that's because they intended it use it to teach and educate people and needed a lot of volume for that. Agilex isn't a teaching part. It's their most advanced top-of-the-line part with its own logic design requirements that differentiate it from earlier lines (Arria 10 and prior.)

You likely aren't going to see "consumer-oriented" Agilex-powered devices in similar form factors anytime soon; most of the compute power of the fabric would be completely wasted without fast peripherals/storage anyway (the fabric can be clocked very high if you pipeline enough) and the shipping volume to make the boards attractive/low-price enough would need to be pretty decent. This means the board would actually end up expensive; why pay so much for the FPGA if all the I/O sucks? But good I/O is expensive. The Agilex parts are some of Intel's most complex devices on their latest "Intel 7" process too, it's not cheap.

I guess it's maybe something that would be possible to crowdfund in low volumes, but it's a truly huge amount of work even before you get to price. Designing the board, getting the software and tools working, documentation, that's before you even manufacture. And realistically there are probably other FPGA options that would be cheaper and more readily available. Something like a Kintex-7, or Arria 10 part would probably do just as well for significantly cheaper, I'd think, but it's hard to guess unless you have more concrete requirements in terms of LEs/memory/clock speeds.

Maybe if you pray they will make an Agilex-D PCIe developer kit that "only" costs $2k USD, requires tiny fans that sound like jet engines, and has 1 HDMI out.
