Mechanically speaking nothing is impossible .However at times you have to get real creative .For example the track rollers on my old Oliver crawler .They were originally made by Atlas track and parts became NLA decades ago .
Track rollers use plain bearings because of the shock loads .Caterpiller uses hard bronze ,Oliver used steel backed bronze inserts .I found that Chevy 350 transmission tail shaft bearings were the same ID/OD but were half as wide and were steel backed babbit like the cam bearings in automotive engines .Using two on each side I was able to save one roller out of 8 .The other 7 I had the correct parts .
Any thing if the demand is high enough somebody will make the parts eventually .In surfing E-bay recently I found now you can get repair parts for the afore mentioned .
