Weren't quarterstaves frequently metal-capped in real life, to avoid splintering on the ends?
Yep, 'twas so. One can easily assume that many quarterstaves in D&D are actually metal-capped, it doesn't really change the damage. The capped ones are probably a tad thinner and shorter, but not by much.
Now, a staff made entirely of metal, but with 'honeycombed' internal structure, isn't all that likely and would still weigh a lot more than a standard, wooden quarterstaff. It may just barely be possible for D&D weaponsmiths to make a hollow steel stave 4-6 feet long, but I dunno.....and something of more complex internal structure is rather unlikely.

I would make it 1d8/1d8. Really it just becomes a heavy mace mechanically... The real question is, does it become a Martial or Exotic weapon?
If the staff's damage is 1d8/1d8 and it retains the normal 20/x2 crits, it would probably be a martial weapon. No way would that be suitable as an exotic weapon (it's stupid enough that kamas, nunchaku, sianghams, and such are exotic; they're freakin' marginally different versions of sickles, light flails, and halfspears (3.5 shortspears)! They don't even do more damage or anything.
The two-bladed sword is exotic because each of its heads has the same stats as a one-handed martial weapon (longsword), but with the advantage of one end counting as light (which makes it better suited to two-weapon fighting, as a double weapon). It's a very minor advantage, to be sure, but that's what the EWP feat gets ya. An exotic version of the quarterstaff would have to be at least equivalent to a pair of warhammers. Wielding a heavy quarterstaff would still be easier and less risky than handling a two-bladed sword or, heaven forbid, an orc double-axe or (far worse) the absurd dire flail. Thus an exotic staff would have to be especially weighty to warrant exotic weapon status.
