Who says that you can't have a 2 way conversation? We are putting 7961s all over the place with default handsets and without disabling G.722. For an intra-region call between two 7961 phones, CallManager will indeed upgrade the G711 codec to G722 by default. Try making a G711 call between two 7961 phones and hitting "??" on the phone. You certainly can have two way audio and use G722 with a standard handset. You just won't get the benefit of hearing wideband audio because the speaker in that handset can't produce the sounds in the expanded parts of the audio spectrum. The phones will stream G722 between them and with the standard handset it will sound just like a G711 call.
That's been my experience anyway.

I wonder if answering on speaker phone would work? I've seen the 7962 as low as $209, 7942 for $162, 7961 for $140, 7941 for $119 all refurbished.
