PDF reader that lets one override fonts

Yeah, I see that. I was hoping they were all 'no' and then you could find the 
fonts you want, rename them (to what the pdf wants) and drop them into 
~/.fonts which should work.

Another tack:
I found a link:http://www.linuxjournal.com/node/1000235
"Handy hint: You can run pdf2ps on existing PDF files and it will change 
embedded fonts to embedded font subsets, usually reducing the file size 
substantially." -- not 100% what you need, but it has a few hints.

So, perhaps pdf2ps then backwards, ps2pdf might just do it? I'm hoping for an 
error and a substitution of local fonts.

They also mention pdfedit (in repos):

And, here, a glimmer of hope:
Go to ps, then back with a switch...
ps2pdf -dEmbedAllFonts=true WonderDog.ps
