Must be a rare bird here. My 50's nostalgic roots love the early GG wide flex track curved three rail and my hard core 2 rail appetite favors 2 rail realistic appearance.
Something that reflected my mixed track thinking is the Brandoywine River Museum in Chadd's Ford PA. They have a huge 2 and 3 rail combined very well done layout displaying the best of both worlds.
With that in mind, I just had to add a couple of 3 rail levels to reflect my life's experience in 0 scale.
In your case however, I would not rip out the center rail, but rather simply add a two rail operation along side the existing trackage.
Consider this, IMO, I see absolutely NO resale value in three rail track with the center rail pulled out. If some one would want two rail track they would not want stripped high rail track with a string of messed up / patched up tie centers.
No matter how much you love your layout, one day it is going to be disassembled. The question remains how much recovery would you like to receive from your expensive track purchases? Typically used track in good to excellent condition sells for 1/3 of it's current retail price. Older track can yield 1/4.
(Which reminds me of one of Leno's Jay walking surveys where yuppies thought 1/4 was bigger than 1/3 because four is more than three.)
In my endeavors I have taken down many layouts and 99% of all the 2 or 3 rail track was resellable.
So if you just want to add some not quite new 0 scale 2 rail track I have 600 feet and 100 turnouts of late model Atlas 2 rail looking for a new home.
