Radiator same side hot water delivery and return water exit

My house was built in 1939 - Quebec City - Canada. Most radiators are 4 tubes with various height and number of sections. What is annoying is that the supply and return pipings are side by side, on the same side, at the bottom of the rad. The heating system is still gravity - two pipes and it works OK!
I contemplate the conversion from gravity heating to hot water forced circulation with the removal of all existing large pipes in the basement. Would the cast iron radiators with the side-by-side supply and return piping work in a circulated system? How should one approach the design of the new system with such radiators?
Thanks in advance
