What you describe is already possible and architected as Create Parition. (What you call an "escape sequence" is called a Structured Field in the 3270 lexicon.) It just takes an application with knowledge of partitions. :-) They're as rare as hen's teeth. With SNA, the BIND lets you set the initial size of parition 0 (the "implicit partition"). Non-SNA has no bind and so no way to set the size to something other than 24x80. A partition's primary and secondary size is fixed for its lifetime.
Perhaps I'm misinterpreting what you meant, but I have software that allows the user to change alternate size on the fly (user issues SET MODEL n (1-5) or SET mm*nn) providing the device supports at least one partition (I decided not to change primary size because I'm lazy, and didn't really see a need for it). It functions as expected on local non-SNA as well as SNA (theoretically it should also work on BTAM, but I never tried it).
