Sure, just add foamies for the layered armor look and get creative with the styling. If the football gear is too much you can take it down to the basic framework to make it easier to move your head while wearing.
I used football shoulder pads and baseball shin guards to make parts of a Borg costume. Worked for me. Also won be 200.00 in prize money. Photo was taken at Las Vegas in Sept. 2001 where I won $500.00 and $100.00 in two costume contests. Costume is complete with flashing lights, speakers
and a tape player. Hope this inspires you.
