Dennis,

You are right, it has been tried before. Some people lacking ext.tubes have
even used toilet paper inner cardboard rolls (or similar rolls) or PVC/ABS
tubes. Ext.tubes are really convenient as you can use a lens cap, as you
mentioned. Your idea is OK, IMO. As for the outcome, it'd depend on what
you are looking for. Resolution on film won't be as "good" and enlarging
the frame willl make it worst (or better if that is what you are after).

So many things to do, so little time, I know what you mean.
