They mean completely different things and have different purposes. You could just get rid of touch and flat-footed ac but there go all touch spells. Averaging is kind of nonsensical. Especially keeping flat-footed in the average. If you average all three you are just going to gimp most martials. There is no point to doing this; they are for complete different contexts.

4th ed D&D used Reflex in place of touch AC. Grappling targeted either Fort or Reflex. Or at least I think it did - it's been quite a while. PF isn't built the same way, so this would be messy to implement.
However, I like having the three ACs. If all three are recorded on your charcater sheet, then there is nothing to be slowed down by.

Actually, lets make this easier... Casters add 1/4 level and casting stat modifier to touch attack rolls (about a +9 to +15 at 20th level).
Flat footed bonuses equal attacker's dex modifier.
Now you have a couple different forms of attack roll to keep track of for PCs.
This isn't even close to the current system, and is either over or underpowered as heck, but it should help with whatever you're trying to do.
