The  8088-2  just  accepts  a  faster clock rate, I think. That is not a
trivial (and perhaps not a possible) option.

The 8086 is a no-no. Different chip, incompatible pinout. It's meant for
a 16 bit bus, the 8088 for an 8-bit bus.

The V20 is usually a plug in replacement and very cost effective. I have
one in a real PC, and a V30  (8086  relative)  in  a  PC  compatible. No
trouble,  perceived  improvement  of  around  25%;  cost  around  $15. A
bargain. The occasional system has trouble with disk formatting  but  at
that price it's worth trying.

The  Norton SYSINFO program indicates a much larger performance increase
with a V20 but it's a biased benchmark. For more details on  performance
of a V20, see a recent issue of BYTE (the BIX listings section).
