It looks to much like an elite, but I like where your going with it. Remember that the sentinels recognized chief as a "reclaimer" because of his armor, so the mjolnir and the forerunner armor suits should have a similar appearance, preferably in the visor region. If you ask me, the helmet makes the suit's "character", and the visor is the coup de grace of the helmet, so it makes sense for the visor to look similar in shape and placement.
