The Nose gear would be easy in that it's a normal 90 degree unit, the aft legs just need to have the rotation point be at the correct location and angle. A normal 90 degree unit would probably work for that one
the sequenced gear doors can be done with electronics. Put electric retracts to move the gear and have servos open and close the gear doors. The gear door sequencer (electronic board) does the heavy lifting to sequence the gear doors
But they would be difficult due to the length of the main gear. The main legs would have to be stiff so that they don't easily bend
