 Unless the 630X chassis is really a lost cause, such as many important and hard to find parts missing, excessive rust, etc.,  it may take as much effort to find another chassis as it would to repair what you already have in hand.  I've found it's often easier to find a good duplicate set then it is a rebuildable chassis, and I wouldn't even contemplate sacrificing a table model to salvage a console unless the console had some sort of sentimental attachment. I'm not sure how much was changed between the two but you could also look for a model 620 chassis, as far as I can tell the main difference was the addition of a shadow meter which could be added from the existing chassis. The factory service info from Philco was pretty good for including parts placement diagrams as well as a matching parts list so it would not take long to make an inventory of what may be missing.
