This is a really cool name with an interesting sound; unfortunately, it's wildly impractical this day and age.

Almost certainly a combination of "syn-" ("with, together") and "tyche" ("fate, chance, luck, fortune"). If so, a more literal translation would be "with fate" or "with luck", giving it a meaning closer to "fortunate, lucky" or "by chance", and making it a relation of "Eutychos".
