Fonts don't get that clever.
Probably not. Do they have any option to set a flag like "the last character was a vowel" which can then be tested when the next character is painted? If so there is a chance of detecting this efficiently without having to be too clever.
This couldn't be done in a font, but could be done in a rendering engine like Uniscribe, which keeps track of characters. Font lookups work entirely in glyph space, so their only connection to characters is via the font cmap table.
