I was wondering, since the 739ER has virtually made the 739 obsolete, is Boeing able to physically convert existing 739s into 739ERs? If so, airlines like CO would be interested in doing so. Also, will the 739ER have its own code, or will it just be 739ER?

You could put belly tanks in a standard 737-900, but that's about as far as you could take it. I suppose that if you were determined, you could cut two more exit doors in it. You still wouldn't have a 737-900ER, though.

Thus far there have only been 52 739s ordered.
Presently, there are 82 739ERs on order, with the CO conversion of other 737s pushing it to 94.
This is a real triumph for the program. Many were thinking the 737 was dead when compared to the A320, punctuated by the loss of a certain German carrier a few years back. Folks were critical of any additional rework of the 737, especially the 739 as a poor stop gap measure.
Well, A320 is still garnishing better sales (it may in fact be the better aircraft of the two), but nevertheless the 739ER has staved off a few in favor of Boeing.
I like the plane because it improves CASM. Anything done to consume less fuel when going from Point A to Point B is fine with me.

when I said A320, I meant the Family. I was merely saying the A320 Family has enjoyed a few more sales than the 737 Family.
CFM56-7 as applied to 739ER has a thrust of 27,300
CFM56-5 as applied to A321 has a thrust of 27,000.
Lets call that a tie...dead locked.
739ER has a range of 5,925 km typical passengers of 180.
A321 has a range of 5,600 km typical passengers of 185.
Slight advantage to 739ER if you need the range. Slight advantage to A321 if you don't. Lets call that close.
A321 has an interior cabin 6" wider than 739ER. That translates into 6 wider seats in coach.
Lets call that 1 to Airbus.
A321 weighs more than 10,000lbs than the 739ER. That translates into more fuel burned.
Lets call that 1 to Boeing.
So, their pretty equal planes. However, the A321 has 639 orders. The Boeing entries, both 739/739ER, have only 146. Clearly, the airlines have shown what plane they think is the better plane in the A321 vs 739/739ER contest. Obviously the A321 has been offered longer, so order comparisons must be taken with a grain of salt.
It will be interesting to note if the 739ER will take away future A321 sales. I don't know of a means of tracking A321 orders since the 739ER has been offered. I don't know which one has faired better recently.
But to answer the thread originators question...doubtful Continental, Korean or Alaskan airlines would be able to ER their standard 739s.

You're not going to be able to get the flat pressure bulkhead in either.
