Apart from defining a UCA-based decomposition, there does not seem to be an easy solution. This would require preprocessing of text similar to what is done for Arabic or Brahmic script layout processing (where ligature and character or subglyph reordering is performed before looking up for glyphs and ligatures in fonts). On Windows, it would require using UniScribe, but for collation, changes are still possible, because the UCA order can still be modified to document these reordering rules.
