I don't mind simultaneous submissions, but using an editor's time and experience to develop a proposal for another publisher is appalling. Even if the publishers both approached you at the same time, you have an obligation to either disclose the parallel submissions at the beginning, or find some other way to prevent one publisher being used to develop a proposal for another.
Hrmph ends.
