Given the existence of this feature in telnet, with its complete behavior 
already spelled out in RFCs the only thing 
left is to map the command sequences into the ssh protocol, which can be 
accomplished pretty mechanically. Actual implementations in the telnet context 
have been available to evaluate for 2 decades. If you go back through the 
comp.sources.unix archives from 1989 or so you'll also find the patches I 
wrote to implement a local command history buffer (ala Gnu readline, but 
obviously different since that didn't exist yet) for the telnet client.

If you need to evaluate how well the feature can work, and how much work it is 
to implement it, then you already have all the information you need.
