I can't help you with the gloves :(  Gloves are a hard thing and are very figure specific. Clothing converter programs don't even do a good job at converting them, and that is if the program has the ability to convert them at all.

So far as the cape and cowl are concerned, those are best used in the cloth room as dynamic cloth so that they move with the position of the figure.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
