Some advice and a lot of first-hand anecdotes and observations from someone who accidentally had a career in the bike business.

Best. Chainsuck. EVER!
We are frequently asked to put together drive trains that technically should not work. Some of them function smoothly. Others grumble and chatter a bit. Once in a while you get one that rejects the transplant spectacularly. This one pushed the limit on gear range and chain wrap capacity for a Shimano road triple. On the test ride it made this three-ring chain knot when I tried to use the derailleur to pick up a dropped chain while still riding. Still pictures didn't capture the intricacy of the tangle.
With due care the bike will behave well enough to meet the customer's temporary need for lower gears.
