Yes, I think it's acceptable. However, the "to me" at the end doesn't sound quite natural to me. Note when I just used "to me" it was matched to a statement of perception: "it doesn't sound", "it doesn't seem", "it doesn't feel like". Then again, if you were to say "to me" at the beginning it would sound better - at the end like that, without a connection to an expressed feeling in the sentence, it sounds tacked on. I would use something like "as far as I'm concerned" at the end of a statement like this.
Still, that is not really your question. The use of "foregone conclusion" is perfect.
