8088 would be awesome too, but I don't know if that's possible.
A smooth range from 286 to P1 is possible with Socket 5/ 7 boards with additional slowdown parameters, such as ultra low FSBs (33MHz or slower), forced Write-through L1 cache policy and Turbo/ De-turbo functionality.
Using a typical VIA C3 or SS7 K6 build won't slowdown into 286 territory. You might get better luck with a VIA C3 Nehemiah, but you lose smooth scaling.
Getting into 8088 territory is possible, too:
