Can I make a greek letter extra-bold, e.g. make strokes 1.5 times as thick as \bm does, in math mode? [duplicate]

How can I get bold math symbols?

I would like to distinguish between a vector of betas and the individual betas

I want to use bold, rather than an error, to indicate the vector

However, I see from How can I get bold math symbols? pointed out by @Werner that there is no difference between \beta and \mathbf{beta} .

However, even \bm{beta} could use a little fattening-up, in my opinion, and the \hm from the bm package. Can I make the beta's extra bold? My current solution is just to use "B" instead.

for comparison, here is the output of

\documentclass[12pt]{article}
\usepackage{amssymb}
\usepackage{bm}
\begin{document}
$\beta \mathbf{\beta} \bm{\beta} \hm{\beta} \bm{\beta\mkern-11mu\beta}$
\end{document}

Use "poor man's bold" combined with \bm. Like this:\pmb{\bm{\beta}}. In math mode of course. This requires the amsmath package.
