It is possible but you'd find it a bit challenging, I suspect. For example,
Arasan's board layout (mapping of indexes to squares) is actually different from
Crafty's and (I believe) Phalanx's. So you'd have to modify Phalanx's eval code
and couldn't drop it right in.

Also, while I think the experiment would be interesting, there are lots of
variablse that affect a programs' overall performance. For example, Phalanx has
a different set of rules for extensions. Maybe its eval works well in
combination with the extensions but wouldn't be as effective in a program
without them.
