#StackBounty: #packages #bold #mtpro xfakebold or amsbsy to get heavy bold for mtpro2

Bounty: 50

This question is a follow-up of this question Increase a bit the bold symbols in mtpro2.

Considering this MWE:

documentclass[12pt]{article}
usepackage{newtxtext}
usepackage[lite]{mtpro2}
usepackage{amsbsy}

begin{document}
[int_{x=a}^{x=0} biggl[frac{1}{dot{x}}biggr],dx]
[int_{1}^{2} pmb{biggl[}frac{ln x}{x+1}pmb{biggr]},dx]

end{document}

with a zoom of 337.5 % (working with TeXworks) the fake bold is imperceptible (you can see the red rectangles).

With a zoom of 1708.59 % we have this:

Is there a chance to fix the fake bold well?

Looking this old question and the answer of very nice user @David Carlisle, there is a trick to improved pmb in amsbsy:

documentclass[convert={density=10000}]{standalone}
usepackage{amsmath}
DeclareMathAlphabet{mathsuet} {T1} {wesu}{bx}{sl}

% I get metafont errors from these settings?
%pdfpkmode{dpdfezzz}
%pdfpkresolution=8000

makeatletter
defpmb@@#1#2#3{leavevmodesetboxz@h{#3}%
dimen@-wdz@
kern-.5ex@copyz@
kerndimen@kern.25ex@raise.4ex@copyz@
kerndimen@kern.2ex@raise.3ex@copyz@
kerndimen@kern.15ex@raise.2ex@copyz@
kerndimen@kern.25ex@boxz@
}
makeatother

usepackage{bm}
begin{document}
fbox{{
$bm n n$
$pmb{mathsuet n}, mathsuet n$
}}
end{document}

Is it a possible solution, and how must be modificated the whole code?
