Homeowner heating loop questions.

Hi There;
I have 3/4" baseboard it's going to be connected using 3/4" PAP (Pex-Al-Pex). I have a toe heater that is 1/2" so I have 2 scoop (3/4" x 1/2" x 3/4") tees to make a 1/2" loop for the toe heater. I also have a Buderus 24" x 12" wall radiator with the recommended bypass valve. My thinking is to put the toe heater at the end of the baseboard loop (Return side of the boiler..) so the baseboard can get the high volume heat they need and have the toe heater loop will get the small amount it should need. Is that sound thinking or should it go the feed side ?? The Buderus valve appears to be designed for 1/2" or less feed and return. Should, could I put the radiator in the 1/2" toe heater loop , if so should I put it in series with the toe heater or parallel with the toe heater ?? I'm thinking that series would be better. If I can do it and series is the best way to do it any idea which to feed first ?
TIA
