did you run mktexlsr?

you're talking about font encodings?

\definetypeface [PalatinoA] [rm] [serif] [palatino] [default] [encoding=texnansi]

\definetypeface [PalatinoB] [rm] [serif] [palatino] [default] [encoding=ec]

works ok; typefaces live in their own namespace

if you're talking about input encoding, you can switch regimes whenever you want
