It is very possible. Many of the Batman suits, especially the older 89 style are based on gluing rubber detail pieces onto a stretch base material, so it is a practice that has been around a long time.
The first thing is you will need to Make a "Duct Tape Dummy" of yourself. There are a lot of tutorials for this process on YouTube and just out there on Google, but basically you'll need to get a friend to help, and it involves wrapping yourself in plastic wrap and then covering that in duct tape. You can also sacrifice a pair of old clothes, but the point is you want the duct tape to stick to something other than you. Once you're wrapped up, you get carefully cut out, and then seal the cut back up with tape. Fill the dummy with cotton batting or foam, or whatever you have access to that can hold its shape relatively well.
Now you have a 3-D representation of you that you can put your morph suit on for modifying. This is is important because the Morphsuit is made of a stretch material, lycra or spandex, and you will want to attach the undersuit details to it while it is stretched out, otherwise it really won't work. You can use contact cement, barge cement, Shoe Goo, E-6000, whatever adhesive you prefer to attach the detail pieces to the suit while it is stretched out to your proportions and it will fit you.
