Can E-Max all porcelain bridge crowns handle the bite force of 1st, 2nd molars and 1st, 2nd bicuspid on lower left jaw?

My PFM molar crowns are unsightly. They're oversized, the metal linings and opaque are showing, and my gum hurt due to high bite. Also, my breath has started to stink since I had them. They've been trimmed already,but some more trimming is needed,so instead of that, I'm thinking of having them replaced with E-Max, just worried about the durability and cost in the long run. 1st molar is a pontic. 1st bicuspid stands on its own. Only the 2nd bicuspid and 2 mentioned molars are bridged together.
