Yes, you should get the same results, plus -merge- will be faster and require less memory -- good point.   
Glad to hear that the -reshape- approach works for you.

Finally, Neil's point about  your 32-bit OS is an important one, and that's the reason I asked you about it.  You paid a premium for extra RAM and Stata-MP, but your still limited by a 32-bit OS -- you should consider upgrading to 64-bit to get all you can out of your system.
