A GAL should also be useful--and maybe a bit more flexible. To emulate
the OC outputs, one can simply manipulate the output enable so that a
'1' output is High-Z and '0' is, well, '0'. I believe individual
oput
tristate control is allowed in non-registered mode for GALs. A PALCE
should also work.
A 20 pin PLCC should fit on a DIP-sized PCB.
