What you propose on the Zenith is a valid approach....Spaekers for zeniths are obtainable and putting a want ad on the antique radio forum will get you more help than VK. Using a choke for the field coil is more advisable but a resistor will work. Check the hardware stores for a good sized rubber or silicone O-ring to replace the belt.

I looked the schematic for the 555 on N/A. The Crosley really has a strange volume control and detector/AVC circuit using a dual volume control.
Try to source that one!
