Left-handed bolt for Marauder ?

[Longrange50]

Could the right handed bolt of a Marauder be modified to be used left handed or could a left handed bolt be made for the rifle without any major changes to the receiver ?

I would like to have the adjustability of Marauder and LH bolt in the same rifle. Being able to shoot from the mag or single shots with the single shot tray is a good mix.
