Ah in that case I suppose you could save the bit you want to import as
xml, and write a little script to go through the pen="???" to modify
them. I can't think of an easier way anyway (the best thing would be a
lua ipelet but that might be more work if you don't already know lua
and the IPE API).

I think you can do it with this regex (after loading the file into $xml):

$xml =~ s/pen="([\d\.]+)"/"pen=\"".($1*69)."\""/ge

Where 69 is your scaling factor. NB: I couldn't quite get this to work
with this regex. It doesn't like the $1*69 for some reason.
