I have a 40-150 slant back and the speaker VC is rubbing.  I tried to align, blow it out, clean it...it sounds like one of the wires in there are lose and just scraping.  Sounds terrible.  As a test, i lifted one of the VC wires from the speaker and connected a 4 ohm smaller fixed magnet speaker to it.  It actually sounds amazing..so much better.  Was wondering what i would need to do to make this permanent.  The original speaker has 36-1483-3 printed on the rear mounted transformer... 

So my questions are...

1-Is this a bad idea...i know it is not original but since it improved the sound so much it would be nice
2-The current voice coil measures 4.3 ohms.  I assume i can use something in the 4 to 6 range...I have a perfect sized speaker that is 2.3 ohms...would that be too low.
3-I know the speaker has the transformer on the back end of it.  I assume that needs to be kept in place.  Can i simply leave that speaker, say, screwed to the inside of the cabinet somewhere and lift the 2 VC wires and take that to the new permanent magnet speaker...?

   

Thanks for any advice.  This radio has had all the caps and bad wiring replaced so this is the last thing to make it sing.
