replacing i5800 flash lites files with those of Wildfire or Hero

---

Samsung i5800 contains Flash Lite 3.1 (Flash Player 9) but actually it only display some content, so my question is: Can we replace Flash Lite 3.1 files with those from Hero or Wilfire? Hero (eclair) and Wilfire (eclair and froyo), both, contains Flash Player 10.1 lite (Flash Lite 4).

i tried it, didnt see any difference.
