Ok,I HAD to comment, even 6 years later. This is from a D&D player's perspective. (If Paizo broke the game mechanics for this item, shame on them.) Every single response in this entire thread is wrong in some important way/s. I sincerely hope this helps someone who finds this thread.
1. Bracers of Armor are Wondrous Items. They are NOT armor or weapons in the sense that applying the armor enhancement rules would effect them. The bracers themselves could be used as a 0 Armor Class item, but the fact they have a wondrous item effect on them makes them a wondrous item.
2. You can literally add ANY effect on ANY item, but some effects would be rendered useless, per game rules. (See below.) You also must meet the requirements - like, have a +1 enhancement bonus on any armor that you wish to add special armor properties to.
3. Per point #2, if you gave +8 Bracers of Armor a +5 Armor enhancement bonus, the +5 bonus would be cancelled out by the +8 already on the armor. You can do it, but it would be a complete waste. It is a type of effect that does NOT stack - just like Bracers of AC and Full Plate +1 won't stack. Bracers provide 0 Armor Class, so 8 is greater than 0+5=5.
4. You can add any other wondrous item effects on the Bracers that you would like, even +8 bracers, but you must pay the cost of adding the effect, plus half-again the cost of A. the new effect or B. the existing effect on the item. (Whichever is less.) So, +8 Bracers cost 64,000 gold and +5 Deflection bonus to AC is 25,000. So, adding The +5 Deflection bonus would cost 37,500 gold.
5. Basically, if you want to add +5 Deflection bonus to AC on those +8 Bracers, it would stack and provide a total of +13 to Armor Class. They are two different types of bonus to AC and will, therefore; stack. It would would be a non-standard item for the enhancement, but an appropriate body slot. (Meaning, you wouldn't typically apply a Deflection AC effect on Bracers, but adding AC to a bracer is generally appropriate.) This can add additional cost, in some cases. You could even add a +5 Dodge bonus to AC later on. All three bonuses would stack because they are different types of bonuses to the same stat. (And, aren't specifically barred from stacking, per game rule.) This would yield a total of +18 bonus to AC.
6. If you want more info, Read the Magic Item Compendium (3.5 D&D), starting on page 232. (Especially, note the section on "Adding Common Item Effects to Existing Items."
