im gonna try to stick a close as i can to the original designs myself . i think your idea is gonna have issues with the wire not being in the center of the cone . i also think the disk is a bad idea . there is no "if" about copper oxidizing when exposed to the elements .

from what i understand the basket doesn't prevent the the lower part of the antenna from radiating . FWIU the vertical and the basket work together similar to coax cable . the vertical is like the center conductor , the cone has a inside and a outside surface just like coax shield . RF travels on the surface of elements . the inside of the cone contains the RF that is out of phase on the lower part of the vertical with that with the top 1/2 or 5/8 wave , but the outside of the cone radiates opposite of what it does inside the cone so its in phase with the upper portion .

hopefully i got that right . id appreciate any correction that may be needed if i am wrong .
