I honestly feel like this is the best route to go. Considering Boba was the only "Mandalorian" in the Original Trilogy, seeing any variant of it other than a kit-bash of multiple colors and found items is a bit...odd. When customs start getting mono-chromatic and uniform, it detracts from the look of Star Wars and starts getting into "Hey...is that a Halo character?" territory...you hear the public making comments like that at cons, trust me.
I'd highly recommend visiting gun shows, militaia stores, etc...find anything Pre-1980 and work on altering it with greeblies and chop-mods. Take long, hard looks at the damage Joe Johnston applied to Boba's armor and replicate that look. Before you know it, you'll have something that looks like it belongs in Lucas' archives.
I feel the most impressive custom costumes are the ones where you look at them and go "Now THAT was something Lucas' team made in the late 70's!". There shouldn't be anything "modern" or "futuristic" in a recent sense to it.
Shoot me a PM on this any time you want man, and I'm sure a lot of people here will be more than willing to help you out! The WANT to self-improve and stay true to the Star Wars aesthetic is 90% the battle.
