As another poster said, the platforms would be adjacent;
however, whether services actually run through from
Wandsworth Road - CJ - Imperial Wharf (& v.v.) is debatable;
for reliability's sake, an Orbirail service may just operate
CJ - Willesden - Dalston - Peckham - CJ and return.
The Circle line is an indicator that circular routes crossing
a variety of junctions perform poorly, as without a proper
terminus it is difficult for them to regain lost time.

The reliability depends on the time allowed at CJ, not on whether trains
return whence they came or proceed around again. (Actually there would be an
impact on reliability of circular trains caused by crossing each other's
path near Clapham Junction, but that would be minor.)
