its obviously a very personal decision, but i think 5 is way too young. my son is 5, and he is very concerned with getting old and death and i know if i brought him to a wake, he could never wrap his brain around it, i know it would completely upset him. and, that aside, why would you want her to remember her like that? i would definitely bring her to see her now, take some pictures of them together, and later on you can look at the pics with her and older pics of your aunt and talk to her about the good things and happy memories, and that is how she will remember her angel. believe me, i know from experience that there is a great chance that if she sees her at the wake, that will always be in her mind every time she thinks or hears about her. and i really think that is the best case scenario, you just never know how a 5 year old mind will interpret these things. and, i should have said this first, but i am very sorry for what your aunt and your family is going through, i wish you all the best.
