Combine multiple pix of same object? = yes
Make it look better? = Maybe, but not automatically
Faster? = faster than what??
You could:
- shoot a set of images with various lighting positions with the camera mounted on a tripod so that the image are framed exactly the same.
- open all of the images in Ps so that each is on its own layer.
- turn off all of the layers except the bottom layer.
- identity the flaws in the bottom layer (unwanted reflections, ...)
- turn on the next layer up to see if it doesn't have one of more of the flaws. If it has a better area then add a mask, fill the mask with black, and then paint white on the mask to reveal the "better" area(s).
- repeat the previous step with the next layer and so forth.
To accomplish #2 you can simply open one image and then, one by one, open each additional image into Ps and drag its entry in the Layers panel onto the first image. If your version of Ps has it, you could use File>Scripts>Load Files Into Stack... and Ps will do the stacking as layers for you.
This is not particularily fast, but depending on your Ps skills it may be faster than manual retouching. How well the sections of the different images fit together will depend on how the lighting changes look and how uniform the exposures are. I've done this successfully with architectural photos to eliminate moving people and traffic.
