In any case, since you use plain xterms, you can create compose sequences that you add in your ~/.XCompose that cover those combinations that dead_circumflex is not supposed to work with. For example, for 'b', you would add the line <dead_circumflex> <b> : "^b" <dead_circumflex> <B> : "^B" These two rules say that when you press the keys before the ':', you get the string after the ':' (the string in quotes).
