What would be the best way to make an adapter for the anode lead? I have a spare anode lead with suction cup. What would be the safest way to couple that with the existing single prong anode lead for connection to the 10BP4?

Yes the door knobs are those caps. The ceramic caps do have a bit more leakage than the glass dielectric of the tube but the capacitance of the tube is usually stated as being about 500 uuf (pf).
I have some people put an alligator clip on the extension and place the joint in a glass jar to insulate it.
