How can I get the regular \mathbb and the kpfonts' \mathfrak using fourier?

Question

I need to get the regular \mathbb style (the resulting one only using \amsfonts) and the kpfonts' \mathfrak style using the package fourier.

Thanks.

Welcome to TeX SX! In my opinion, you shouldn't: they don't fit well together. — Bernard, Sep 23 '16 at 02:17

You shouldn't and I wouldn't, but technically you could.

\usepackage{amssymb}
\usepackage{fourier}
\DeclareSymbolFontAlphabet{\math@bb}{AMSb}

This is entirely untested since you didn't provide a minimal working example - or, indeed, any code at all - to work from. So you must be happy adapting it to your local requirements.

You can; whether you should is a matter of opinion.

\documentclass{article}
\usepackage{fourier}

\DeclareSymbolFont{AMSb}{U}{msb}{m}{n}
\makeatletter
\DeclareSymbolFontAlphabet{\math@bb}{AMSb}
% see http://tex.stackexchange.com/a/254979/
\AtBeginDocument{\protected\def\mathbb{\math@bb}} 
\makeatother
\DeclareMathAlphabet{\mathfrak}{U}{jkpmia}{m}{it}
\SetMathAlphabet{\mathfrak}{bold}{U}{jkpmia}{bx}{it}

\begin{document}

$A+\mathbb{A}+\mathfrak{A}$

\end{document}

When I use the MnSymbol package the command \mathcal{P} shows a nice P, but when I remove that package, \mathcal{P} shows a very ugly P (in my opinion) thanks to fourier. How can I get the normal P whitout MnSymbol using the \mathcal{P} command? – Diego D. R. Rivera Sep 27 '16 at 06:16
@DiegoD.R.Rivera You should be aware that MnSymbol changes all math symbols. There's no ”normal“ P, so it's quite unclear what you want to achieve. In any case, it is a brand new question. – egreg Sep 27 '16 at 07:17
