I'm not sure if you're using Epic Defensive Fighting (which you get for free), but if you're not then just using that free feat will give you more HP than these lost 6 feat slots. When it comes to survivability effecitive hit points is more than just your raw health and, if you want it, then you need to be incorporating that into both your gear and enhancements (both heroic & epic).
Realistically these are tank feats. The rate of return on damage reduction from PRR//MRR is x/(x+100). For these three feats you're getting 37 rating (27% reduction). A sheltering item cannith crafted at your level would do 36 base, and 17 insightful rating (34% reduction). If you keep the feats, and run the sheltering item, you'd have a combined 47% damage reduction. It should be noted that Epic Damage Reduction's +10 PRR boosts these numbers by about 4% each to 31% and 50% respectively, but that's a combined 4 feats of opportunity cost. Between this and Toughness spamming though, the damage reduction is obviously the better return on investment for survivability.
However, it is ultimately the opportunity cost that is what the value of feats comes down to.
Some feats that create opportunities that got overlooked in your initial build include the Cleave feats (for trash & adds), Stunning Blow, Improved Trip, Tactician & the Tactical Training feat-line, as well as Magical Training (which gives Echoes of Power). I don't have a specific build to give you, that says "Pick these feats for to do this content", but rather would encourage you to think about all the times you were inconvenienced by the lack of utility from a given situation you were in, and look at feats to eliminate that inconvenience.
Looking at your build I can feel the amount of time, from my own lives as fighter, just sitting around doing jack **** while you auto-attack down some mobs. In the epic levels the epic destinies provide some nice attacks you can use to fill the gap, but you never get so many that the above feats would be completely pushed out of rotation. I would suggest starting by eliminating some of the excess health you have from Toughness Feats, and add some self-healing through an epic destiny if you're concerned about survivability.
