I love the Nishi set.
I'm totally biased but I wish that was the default set instead of the alphas

Drop already offers a set including nishi, the corresponding red colored space bar and a couple of novelties (gold return/gold escape key/novelties shifts). Then the colored F keys if you choose the TKL option. There is also a 65% and an ortho kit option.
https://drop.com/buy/drop-redsuns-gmk-red-samurai-keycap-set#overviewIf you want this for a TKL or smaller keyboard, the pre-set is a really nice way to shape things up with the current custom keycaps drop. If you combine both of them, you can basically cover up an entire TKL keyboard (100$) with novelties (+55$ or +45$ if you for text novelties). Then if you want the gold spacebar, add 20$ to all of this. That pretty much covers up everything for about 175$ if you take everything. For a quality and popular GMK kit like Samurai, it's a pretty decent price I think. It's definitely a much better deal than going entirely through the custom drop with Base kit + Nishi + Novelties + Spacebars (125$, 65$, 55$, 20$...)
https://drop.com/buy/drop-redsuns-gmk-red-samurai-custom-keycap-set/talk#discussionsIf the blue version of Samurai interests you, I have opened up a discussion with Elbert of Drop regarding the same possibility:
https://drop.com/buy/drop-redsuns-gmk-blue-samurai-custom-keycap-set/talk/2643935I've also asked if it was possible to receive a confirmation Drop will do the same preset in blue color before the custom drop ends. That way, we know if it will be a possibility or if we have to go entirely with the custom drop.
If you want Samurai (either blue or red) for a full keyboard, then you are pretty much forced to go the custom drop route and pay for everything as there is no pre-set option for a full.
