I was thinking of following case:

* my WindowsXP has old usp10.dll which does not support
  a few Indic scripts like Khmer, Myanmar, etc. Or, my
  OpenType fonts are incompatible with Uniscribe. However,
  fontconfig-based text layout system works well.

* most of scripts are supported well by old usp10.dll and
  fonts bundled to WindowsXP.

* as a result, I want to render most scripts by Unicode
  (inc. Arabic, Hebrew, etc), but I want to render a few
  exceptional scripts by fontconfig-based renderer in Pango.

Is it possible to configure the text layout engine for each
script, when Uniscribe is used by default?
