I tried, in fact i Have access to the kl files of the device, however, if i change the values in ics keyboard stops working, probably they keymaps are stored in the kcm file. The problem is that I cannot extract the kcm file, or better said, I can extract it but not repack it again with new values. In Gingerbread however I can edit the keymaps quite easily using the same method. Strange.
