Are you sure that is what you meant to say ...

Correct

Yes ... but we need to define what you mean by 'painted to the screen'
If spacefill is turned off, then the atoms are not painted to the screen.

Agreed

Only the bonds get drawn.
Not that I just implemented
star on|off|{size}|percentage
To support bonded atoms. One can say
select *; spacefill off; wireframe; select !bonded; star 20%

I suppose that it is not too bad.
Q: Why do you want this?
