I don't know what construction technique you have in mind, but I prefer to
build them from 1/2" copper pipe. If that's what you intend to do, then
just cut the vertical radiator 5/8ths instead of 1/2 lambda. Build the
rest the same (1/4 wave stub). Attach your coax to the stub section using
hose clamps, and tune by sliding the clamps up or down until you achieve
best SWR. Works great.

Should it be that simple?

It can be.

I understood from other posters that it will not
work with the 1/4 wave stub..

For some posters, a view of the forest is obscured by trees. A j-pole
is a quarter wave stub with a 1/2 wave (or longer) radiator attached
to one side of the open end. The feed is connected nearer to the
shorted end of the stub. Build it and they (the QSOs) will come. Get
it up as high above the roof as you can.
