No,
They are incompatable with several mods and huge pinout difference.
Also the 8155/56 are 8085 muxed bus parts and the 8154 was
National microbus (not muxed).

I'll look later for the INS8154, but the Intel 8155
and 8156 were both
RAMs
with 16 bits of I/O controllable on a bitwise basis
like the bits in a
6821
. . . Could one of those work?

any
This is a National Semiconductor I/O-chip with
internal RAM.
I don't think you will find easy replacements because this was
a very NS-only chip with no second sourcing.
It was used in Science of Cambrigde's (Clive Sinclair) MK 14
