I've seen combis with secondary return but I think they are specifically designed to accommodate a return.

Which combis are those mate ?

Cant remember quality, I'm no boilerman.
I used to get a ppm job to monitor flow/ret temps.
Came accross this boiler in a commercial site and after scratching my head for a while, I rang the boss. He confirmed it was a combi with a secondary return.

Like I said, I'm no boilerman but I think it might have been Ariston or Bosch.
