I've seen the results of attempts at that. Let me put it this way -
try it right before you are ready to pitch the whole mess.
there's not enough pressure to make contact between oxidized traces
printed on mylar and any kind of wire. The mylar sheeting is thin
enough that you are more likely to perforate the mylar than "melt a
channel" _Perhaps_ some kind of foil overlay might work, but it would
have to be akin to gold leaf, and you'd need a solder alloy that
melted below the temp of the plastic to get any sort of joint. For
that matter, if you had an uber-low-temp solder (200F? 300F?), you
might be able to overlay entire traces with WW wire, but not if the
plastic develops holes.
