But or not but

[rmb]

Hello. The diverse uses of the word "but" in english may be a little puzzling for a foreign speaker. Would it be correct here, for an effect of emphasis or politeness or literateness to say:
"Would you have the goodness but to warn me in the first place?"

Thank you (I mean, for the answer...).

Whatever effect the word but would have in your example sentence would be overshadowed by the confusion it causes. In my opinion it would be better to omit it from that sentence. It just doesn't belong there. 8)
