I'm not sure that I can help very much, but I see that you haven't had any replies. The questions are not quite clear to me, but I'll try.
As far as I know you can have a D200 Expert upgraded to a D220 Pro CI, as you are considering. By 'interesting' I think you are asking if this is a wise or smart or recommended change- is that correct? If so, I suggest you look for threads from the fall of 2016 regarding the Pro series sound quality. That will give you some opinions about the changes many of us commented on with the Pro upgrade. As far as a dual mono Expert to a single Pro amp, I just do not know what to advise. I don't recall anyone making this change. Most D400 owners did the full upgrade to a D440 Pro. Both the master and companion D200 amps come back as full D220 Pro models, so there is no longer a 'companion' amp.
I'm not clear on the question in your second post, just a few minutes ago. But I don't think you can send them a D400 and get a single D220 Pro back. I think the idea of selling the companion and doing the D220 upgrade is good but I cannot say if the change from dual mono to single stereo amps will be a down grade in any way. Doing the full upgrade to a D440 Pro CI is probably the best long term solution.
The selling price seems to vary a great deal depending on where you are, and you have no location or system information in your signatiure, so that makes it much harder for others to give you any advice based your location or system. Perhaps you can help us help you with more detail.
Good luck with your choice.
