Having just made "that" decision a few days ago myself it is still really, really raw. However my girl had osteo.
Maybe you have already covered this but I didn't see it... How about if you just lay some yummy tidbits on her bed, no bowl, no stand, just on the bed itself, and then go about your business. It may be that after a while the temptation would get to her. At this point I would just give her whatever is yummy, I wouldn't worry about dog food. Stuff like shredding roast beef, boiled ground round strained, baked chicken shredded (no skin or fat), mac & cheese, vanilla yogurt & Rice Krispies, you could try a combo of mashed potato with the meat, hot dogs, Gerber baby food sausages. Sorry, I know there are more but they just aren't coming in my head.
For dog food EVO95 cans have an average of 500 calories per 13 oz can, so pretty calorie dense.
No one can help you with this decision, nor should they. I know how hard this is.
